It looks like this is the same handheld scope that Radio Shack sell
in the US. Its 80 dollars list over there but Radio Shack at the Twin
Cities Hamfest had one for around 60 dollars.
My wife bought me one for my birthday, not fast enough or flexible
enough for serious use (so am still looking for a scope and
following this thread with interest) but having something the size of
a logic probe with a little built-in backlit LCD showing a scope
trace is an interesting and useful tool in it's own right (even at
the very low resolution of the LCD). Pity it doesn't have built in
battery so it is completely stand alone. Then it really would be the
scope to use checkinging the ignition timing on your car!

I've been seeing ads recently for the HP 'LogicDart'. Looks more like a
meter/logic analyzer than a scope, but it might be worth checking into.
Portable, runs off batteries, and samples at up to 100 MSa/s. It's listed
at $795 (!) in the new TestEquity rag, so you're gonna pay for portability.
It looks like it's about the same size as an HP-48 calc, so it's not as
tiny as the rat shack toy.
Haven't used one, but the HP mixed signal scope (54645D) looks like it
would be a real winner for embedded design. It's a cool $5k though.
HP Logic Darts are pretty cute, but for high speed stuff, still
doesn't quite cut it.
We have a few here, but I usually use my 300 Mhz analog scope or
1G storage scope. Course...I usually work with stuff at 100 MHz

you can capture a snap shoot of 1 sec and then soom trhu all the snap

many other nice litte futures.
I have the digital pods, already conected to my pic emulator, so
at all times i can see all 13 i/o lines of 18pins devices. and then you
are left with the 2 analog for something else, and you can see the
in time of the analog and digital chanels.
