Let's not forget the HP LogicDart if you're looking at small
hand-held scopes. It's quite a bit pricier (US$800) than what you've been
talking about, but so far I'm quite impressed. (I was fortunate enough to
win mine in the Microchip Designing for Dollars contest).

        The LogicDart is a hand-held logic probe/voltmeter/frequency
counter/single channel logic level scope or else a three channel logic
level scope depending on how you configure it. I say logic level because it
basically is only able to show highs/lows - perfect for PICs. It has a
third 'intermediate' or as HP says tri-state level, but basically it's a
two state machine. Good to 33MHz...  A real Swiss army knife in the one
package - pretty nice if you're only allowed one instrument on a desert
island...Check it out.
