PC / USB Port based Oscilloscopes

other USB scopes? They look like a good value for a low frequency/resolution device. Thank you for your helpful response, TomC

Any opinions???

Thank you, TomC

For audio frequency ranges, (but not down to DC) take a look at Daqarta

USB scopes, in general, don't have high enough sample rates to be really useful for signals in excess of 10 MHz or so. USB logic analyzers are (can be) fine but if you need a scope, get a scope.

Well, there is Picoscope which makes reasonable devices and Agilent has a whole range of professional USB scopes. You can even connect them together in a rack.

Somehow, sans any specifications provided, that your existing sound card may do as well.

Yes, I'd forgotten about Picoscope. Might be a handy thing to throw in the laptop bag.
