If the OP is looking for a new scope that's cheap, here at McGill, we've been using the PicoScope USB scopes in the EE labs (DSP Hardware). We trust undergrads with them, and they're a heck of a lot easier to store (if you have 10 of them in a lab). No knobs or buttons, just 2 BNC and a USB-B on a white box the size of a hardback book. Unfortuantely they are Windows-only, so no use for someone like me who's only got Mac and NetBSD at home. And it's quite possible to find a good used analog scope for less, I think, but a digital storage scope has some advantages... Joe.
