My first digital storage scope was a 2430A. It had a nice feel to it, but as nctnico said, the trace memory is very shallow. I also found the maximum sample rate of 100 MS/s to be too slow. Even though the front end is rated at 150 MHz, the low sample rate essentially makes the single-shot bandwidth about 40 MHz max, so you can barely capture a non-repetitive 8 MHz square wave.
If you decide that you can live with the limitations make sure you see that all tests pass on the self-test screen and verify all input channels operate before spending anything on this scope. It is also rumored that if the internal battery dies (and it is more than 20 years old) then you will not be able to calibrate it to return it to service without some serious equipment.
