alright, first of, search ebay. i have 3 top end german 16mm cameras and 4 8mm and super 8mm. all for under 100 bucks a peice. most of them are people with cameras their family had back then and ffigure what the hell, get 20 bucks on ebay. but i researched cameras for about 4 months before i finally got mine, i looked at the sonys, canons, panasonic, jvc, and some weird japanese brand.
with the sony's, they look like a nice camera, but your paying too much. they have a very high tendency of breaking. sony just looked more into the lets cram it full of useless features. and when you film on it, once its on tape...it just looks really digital. they cheaped out on the lens. but, it does have nightmode which is something i wouldnt mind having, but at the time not worth the extra 700 bucks.
with the panasonics, they are SUPER nice cameras, they just cost way too much. and are too limited, you need to keep buying things to expand its useability.
this is getting way too long, but in my opinion, the canons are the way to go...they are just a camera company. where as sony is trying to capatalize everything...same with panasonic, they cant concentrate on cameras as much as canon. the canon has the blue florite lens, which makes it an amzing picture. in my opinion, for the least amount, as far as a top end consumer camera goes, the canon gl1 or 2 blow any of the others away.
oh, and you can get 16mm film from kodak, check their website its pretty cheap. and they devlope it for free with the purchase. and you can have it transfered to digital discs so you dont have to find a way. hope that helps.
