It depends on what you want it for.

I think there's a big difference between the analog front end up a =20
good oscilloscope and the input buffer of a typical "data acquisition =20
board."

I think there's a big difference between a calibrated and trustworthy =20
test instrument and a "demo program" that displays acquired analog =20
data (check out the funky "time per division" values, for example!)

A dual trace scope is much more useful than a single trace scope.

I'm not wild about requiring my PC to be part of an instrument...

That said, there's an awful lot of useful things to do with a scope =20
that don't involve precision, or extended input voltages, or anything =20
beyond "yeah, that looks about like what ought to be there."
