The Minolta SRT101 is common and cheap on the secondhand market. I got mine cheaply (35 USD for camera body, 25 for lens). Lens as received is in great shape, but camera body had multiple problems, starting with a reflex mirror which wasn't returning.

With top cover removed, and some of the strings undone in preparation for a deeper dive. There's quite a system of strings and pulleys used in the light meter, and to provide informational viewfinder displays, shown here with strings undone in preparation for a deeper dive.

Leatherette body covering was held in place by some rock-hard adhesive which still maintained a death grip after all these years, and peeling the leatherette off was a slow and tedious process. But once removed, the mirror box and main body castings separated readily enough. Self-timer assembly is visible in bottom right of photo, and since it's only accessible when mirror box is removed, it seemed like a great time to clean and lubricate it.
Part of the camera's problems appeared due to general need for maintenance (clean, lubricate, replace rotted foam), but there were also some impact damage to be dealt with, some of which was causing the shutter to bind. Took me awhile to figure out just where, but once located, the fix was quick, and shutter + mirror were working great again.

Galanometer needle is visible in viewfinder of camera as part of the built-in light meter, but this one was frozen in place. Struggled to open the galvanometer's housing due to more rock-hard adhesives, and quickly discovered the source of the trouble: Permanent magnet (right) was supposed to be attached to frame of galvanometer, but had come loose, pinning the delicate movement to the wall of the housing. Although I managed to reattach it and reassemble the unit, galvanometer needle is not moving as smoothly as it ought to, and current draw seems excessive, so I think it's simply too damaged and ought to be replaced.

I'll look for a replacement galvanometer, but meanwhile, the camera is otherwise film-ready.
