Cool NB vs MSM vs Ebay special. Which rad to get?

Did a quick search and didn't find anything more than just "he said she said" type info, so I thought I'd run it past you folks:

What kinda difference would be expected between:
Stock NB2 radiator and fans
MSM radiator and fans
Egay radiator and "slim" fans.

I'm looking for efficiency and capability to cool better on a budget.

I've heard people say the MSM rad fits like .6L more or something and has a slightly thicker core due to this. Looking at pics the fans/shrouds look very different from a regular NBs.
I've heard people say that FM did some test on them, and said they're much better than stock nb ones, and even better than some aftermarket ones. Searched around for proof of this info, but didn't find anything.

Then there's the "ebay" version that is all aluminum, is dual row or whatever its called, and has those thin universal fans that come with it. Its obviously bigger and probably fits a bunch more coolant, my question is whether its heat dissapation qualities are as good as say, a koyo or something name brand, or is it just simply "bigger" and not much more than that? Also the fans might be rated at 1000cfm, but the universal shrouds they come in look like crap, so I do kinda question their ability to provide the airflow a stocker does.

Which one would be best? Keep in mind we're not discussing the ultra awesome crossflows by fm or trackspeed or anything "BALLER STATUS", just the 3 mentioned in this post.

Please provide your input, since I'm getting ready to replace my damaged stocker with one of these.
Thanks

I have heard good things about the egay radiators. I would pick that before I would go with any radiator with plastic endcaps.

/\ This is excellent info about he msm, and exactly what I was looking for. Thanks.

So now the question is: MSM or Egay?

If it makes a difference to you, the stock MSM fans are dual-speed and will require some creative wiring.

I was afraid of that. Is it a PITA to wire in?
For the record, I have the stock nb fans that I was kinda considering re-using with the MSM fan blades and shrouds. From pics it looks like they should bolt right in. No idea if that's true tho

My cheapo Mishimoto has held up very well the last 3 years. I vote Ebay rad.

The MSM fans are kinda thick. They make working on the front of the car a pain in the *** (even before I bought my KOYO). I'm eager to get rid of mine. I have the Koyo 55 with stock fans and I had to trim the bottom of the fan blade and shroud to clear the ARB. The dual speed part I'm not sure is worth it, unless there is a magical benefit to a lower speed that I'm aware of.

I picked up a great condition Mishimoto rad for 75 bucks. So far so good. The construction seems pretty damn decent.

Vladzor, are you planning on doing a coolant reroute? Ever think about buying a high quality fan shroud and using it with the OEM rad?

It's probably not worth the hassle, MSM fans have dual windings and I think 3 relays. There's wiring diagrams on m-s.com that would help if you feel brave. Everyone that upgraded to the FM fans wired it so both turned on together.

Crap.
Well, that pretty much kills it for me then. I thought it was a simple plug in affair or at worst just a quick splice job, but if it requires more than that, its just not worth it for me to go the MSM route.

What I have is a slightly damaged NB rad and 1 cracked shroud. Hence my dilemma:
replace stock rad/shroud,
replace rad and both shrouds with MSM (being sold locally for a decent deal),
or just get one of those egay special dual-row all aluminum rads.

So far I'm starting to lean toward the all aluminum and either get the ebay slim fans with this shroud they sell em with, or just slap on stock shrouds/fans.

I have the ebay radiator and am buying the ebay fans and shroud now.

If it's good enough for me it's good enough for you.

A fu'd up data point:

I have been driving around with no fans for a while. 220* on a big ol' pull. bleh

I'm also looking for a new radiator. I was looking at the ebay dual row aluminum one for $115 without fans. My question is will the stock nb fans mount right up or is there extra fabbing involved?

Well the tabs on them definitely look like they'll fit/work.

Post links for what you guys are looking at? I'm seriously considering pulling the trigger on a radiator.

Those make me go "meh" because they aren't using stock size hoses, Flounder. Even says so in the ad.
