I'd avoid anything with that low of a bandwidth. Shoot for a minimum of 100MHz bandwidth. Digital is nice, but if you're troubleshooting an analog circuit, such as the IF in a BitX, the signal is constant and will always be onscreen anyway.
Remember when buying used, most of those old Tek & HP scopes out there are more than 30 years old. Caps are beginning to dry out but if you can get one that has recently been re-capped, that's the way to go, but I'm a bit biased. 7 of my 8 scopes are Tek ranging from X-Y to 1GHz. The one non-Tek is a Motorola and the only reason I have it is because it's part of my service monitor.

It's only 20Mhz but would have some application. I have been using one
for years in robotics industry and has worked flawlessly for me.

While on the Circuit Specialists web site I came across this:
Hantek 20 MHz USB Oscilloscope for PC.
Is this something that could be used for radio troubleshooting? Have
never used a scope before and would appreciate your comments.
