I just bought an $60 analogue model from 1976. 30 Mhz, dual channel, takes a minute to warm up...It's awesome. :) I have used it to develop AVR-projects, and I just don't see why I should have more Mhz than this... the signals I analyze are usually only a few kHz, and even if I wanted to I could analyze the 10 Mhz signal that the PIC/AVR is likely to max out at. Could you who say that "don't go below 150Mhz" motivate? I cannot see why I would be better off with a $400 oscilloscope... I can have a lot more fun for that money... On the subject, 200 kHz would be a bit low... There will probably be times when that is not enough even for a simple project. And for that price, you can get one of the above.
