I think the main issue about this class of cameras, is , yes they were auto focus/exposure/etc., so they could be used a an oversized point and shoot, but if I recall correctly, most of the autofocus schemes on these cameras was not so great compared to what we get today on modern digitals. I am sure there are exceptions (maybe some of the Nikons for instance), but for $9 I would not expect much and would rather get another Praktica body or something similar (not that I need one).
My Fujifilm XT-2 has all the features I could have dreamed of when I was young and could not afford the motor driven OMX's/Nikons/Canons/etc. with fancy zoom lenses, and 50' film backs, etc. And it works very reliably, even very reasonably quick autofocusing (for my shooting style). But 50% of the time I am more than happy (and even enjoy) just manually advancing the next frame. The other 50% I use the XT-2. And yes, there is some plastic on the XT-2, but is is a very solid camera, and metal where it matters.
Auto-exposure is nice, but for me only with visual feedback (i.e., digital)- other than P&S. I usually end up searching for the right exposure, and still need to think about it to avoid blowing out clouds, etc.. With manual cameras I use a light meter and think about it (takes a little longer, but for most cases, not an issue).
