I did use their advice on how to get the hose through the "collar" with a small screwdriver, though and that has made making hoses easier. I haven't re-cut a hose end since (before, if it wasn't perfect and thus easy to slide the collar over it, I would re-cut the hose to get the collar on).
I've thought about DIY versus taking measurements to a hydraulic shop. I guess in the end, with having DIY/varying turbo setups and not having repeated and known measurements/lengths, being able to assemble one end of the hose, route the hose and cut to length is the advantage. I suppose, once you have made the hose, you could it take it somewhere to have a shop make a copy with crimp-on ends but I'm not sure it would be cheaper, plus with the crimp-on ends, you can't replace the hose if you do have it burst and have to get a new hose and hose ends. If you really loathe assembly, you can find a local shop to do it for you but it gets easier the more of them you do and that video did really help me more than Carroll Smith's fastener book, although he does discuss quite a few good things in it about plumbing.
As for the Summit hose ends, I have a few of them on my car. They seem to be okay. I've mixed and matched hose with several hose-end manufacturers with no problem. My AN-4 line was self-built from pieces and has held pressure so far.
