OK, so it was 200Khz then.

Personaly I have a HP54602 (150Mhz, 4-chan) I bought for
350 EUR (about $380). Works great.

200kHz is ok for audio work, but you need more speed for logic debugging.
I wouldn't feel comfortable with less than 100 MHz.

The TEK TDS-420A is what I use.  DEEP memory for one-shot events, four
channels, which is enough for most problems, and great analog performance.
The ability to save waveforms to disk is really handy.
It's NOT cheap though, a decent used one goes for about $3k.
