Cheap, not afraid or no regrets if lost, cheap, throw it ion a bag, cheap and oh yes, cheap. Just hit the local thrift shops. It seems most have a $5 bin loaded with older film cameras from early through late auto everything. On my last trip to one there were a dozen or so offerings and I picked 2 that I thought may be of some interest. The first was a Canon AF35M. I learned after the lens is supposed to be good but its auto everything except the ISO settings. A prime lens of 38mm with a filter screw of 48mm. Runs on AA batteries. At worst a glove box keeper.
The 2nd is a Samsung Maxima 105S. Not much found on the web. Uses a CR123 battery. Zoom from 28mm to 105mm. Again auto everything but this uses the DX coding and there is no way to vary the exposure. But for $5 what the heck. Both have built in defeatable flash.
The Canon is a decent to hold and the controls are well placed. I've not gotten a roll through it yet but as the reviews are decent as to the lens, I suspect it might be a daily carrier. The Samsung sadly is an exercise in poor software programming. I can turn off the flash after hitting the flash button a few times, have a portrait and landscape mode and even a "fuzzy" mode (not sure what it does). BUT, after every shutter trip or turning it off and then on, the setting default back and I have to reset them for the next shot. A pain in the arse as I do not use flash. However, on the plus side it does have a decent diopter adjustment. The feel is not as good to me as the Canon but not bad.
No, neither are up to my Leica by a wide margin but for the price and expecting them to be abused to the point of destruction they are worth it to me. Either should do the trick. I also think with a little gusesswork, and looking there are a lot of these throwaways that are okay users and cheap.
