I recommend any of the Tektronix all-transistor (or IC) portable analog scopes,
100-350 mHZ. I've got numerous ones, including several 2235s. I got the military version of the 2235 (AN/USM-488) at the last ETF swap meet for $75. But for the 2235, make sure the mode switches work before buying, as they go bad.
None of mine have ever been calibrated, and all are still plenty good enough for our purposes.
