The best oven I could buy for my bakery is literally the cheapest Oscilloscope cost....that is stupid expensive.
</p><p> </p><p>thats why i rock a used one of these (from the 80s?), which still go for well over $100 on ebay if its in good shape</p><p><img src="http://cimg0.ibsrv.net/gimg/www.miataturbo.net-vbulletin/1050x788/80-tektronix465_864f35b3c5a37cce880f0f6e96fa886e99faa dc0.jpg" title="" /><br /><br /> </p>

Digital scopes are significantly more useful than analog ones, IMHO. They've also gotten pretty cheap on the low end -- a Rigol 1052 is a 2-channel 50Mhz DSO and runs $300 brand new. 50Mhz may be low by gigabit ethernet standards, but it's still about 3 orders of magnitude more speed than you'll need to look at any signal in a Miata.
What is the 300k one used for. What needs such precise measurement of the rate/flow of electricity. I can probably think of a couple very narrow applicable fields like MRI machines or Cat-scans but what are they primarily used for that people are buying them in quantities that 300k is "fair".
