I've bought 2 CRO's from eBay:

- Tek 465 - 2 channel, delayed sweep, 100Mhz, about $200

- Tek 2246 - 4 channel, delayed sweep, 100Mhz, cursors and measurements,
about $500

The first is a bit cranky (mostly needs a bit of contact cleaner in pots and
switches), but the other is very sweet.

Well worth having if you do any amount of hardware work to speak of. It'll
save oodles of time.
