I like the idea of the scope on the computer card except for the hassles with portability. If I got a PC based scope I would want one I could use with a laptop. Is the PC scope as versatile as a stand alone unit or do you lose other functionality?

The A/D capture for use as a recorder would also be nice sometimes.

I probably should have said that I would buy one used. I wouldn't use it enough to justify the cost of a new one.
