>>3723594>I wonder if you can find these kind of deals with SLR.You could but it's not like they're everywhere like they used to be.
The best "bang for buck" is autofocus SLRs. Elan 7 is around 100€ and has tons of modern features, with regards to metering modes, AF modes, etc. . If you want a basic film Rebel you can get those for €50 or €30. And then you can share lenses with your digital, they'll autofocus and work perfect out of the box.
Do you want something different? Like manual focus or rangefinder or something?
In general the jump from ~50€ to ~100€ in film SLRs buys you a lot of camera, and above that it's mostly diminishing returns. The sweet spot I'd say is ~100-150€.
Also, you mentioned batteries. Film SLRs come in 2 broad varieties, the ones with mechanically controlled shutters (controlled by springs and clockwork mechanisms), and ones with electronically controlled shutters (controlled with electromagnets and circuitry). The electronically controlled shutter ones, obviously need batteries to work. And some features, like aperture priority, need electronically controlled shutters. Keep that in mind when looking for cameras; as a rule of thumb, if it has aperture priority, it needs batteries.
Some higher end models offer a (usually single) mechanical shutter speed as backup, usually 1/60 or so (and bulb).
Since you checked the ME Super, check the Olympus equivalent, the OM-2. (Or better yet, the OM-2SP which is underrated imo).
If you liked the size/feel of the ME Super but would like mechanical shutter that doesn't need batteries, check the Pentax MX. Or again the Olympus "equivalent", the OM-1.
Usually you get a bette price when buying with the standard 50mm lens, and the next best value for money lenses are the 28mm and 135mm.
Prices are all over the place, so check what prices *you* can find, including shipping.
For instance I stumbled upon a mint looking OM-2SP, with the 50mm f/1.8 and a T20 ttl flash for 75€.
