As this just uses the microphone jack of a 16 bit sound card as input, this would be the cheapest way for me to scope an output of a PIC (Actual, real live 'scopes are out of my price range)

Ross,

I have tried some of the "oscilloscope" software some time ago and came to the conclusion a simple LED would do almost the same job.
The "software-only" solutions are ways too slow and many features are missing.

Have you searched ebay for an oscilloscope?

I have got a Dual Channel 20MHz Scope (including 1 good Probe) for $50 on ebay.
