Well if you want to go cheap, get a Nishika 8000. There are tons of these things around so they sell for less than the Lomos, and the outer pair of lenses have decent stereo separation. The 1/2 frame format will also cause less confusion for processing and you get get mounts compatible with most viewers. Compared to the Lomo, you also get a whopping 3 apertures to choose from and a little light to tell you to use flash. (Yes, that's all the AA batteries do; the "LCD" on the top is just a sticker.) Oh, and a lead weight and psuedo-SLR styling to make it look like a more serious and expensive camera ;-)
