I got very lucky a couple weeks ago and scored a basically pristine 7104 and it's intended plugin complement at a .gov surplus auction for a very good price (all of the above for $125). It is obviously well cared for, as the crt is crisp, bright, with the only signs of any problems being around the readouts, which are a bit dim compared to the traces (which isn't unexpected I suppose). I've found it is very easy to get a perfectly usable trace for all but the fastest signals at very low brightness levels...low enough that the limited view circuit either isn't kicking in or it's in the 20 minute timeout region (beam current above 0.2 microamps, but less 2 microamps) than rather than 2 minutes (2 microamps or above).
It's truly a tour de force for Tektronix analog scope engineering; beautifully crafted inside and out, with incredible performance.
