Cheap Underwater Photography Questions

This is probably pretty trivial, but I was wondering if anyone had any recommendations on disposable/cheap underwater cameras. I'm planning on doing some snorkeling in the Bahamas, and the only housing for my Canon S2 IS is a $700 Ikelite model. So instead, I have a couple of options :

1) Get 3 or 4 underwater disposables. There seem to be two main ones - a Fuji and Kodak. Neither has a flash, both use 800 speed film. Probably just documentary shots I'd guess.

2) Get a cheap waterproof 35mm film camera. I've found a couple I'd be willing to pay for if they are worth it, this one and this one. The big problem I see here is that I'd probably want to change film - which sounds like a bad idea. I've only snorkeled once and I'm not sure whether I'll have a boat, or long swim/walk to get to more film.

Any suggestions? Thanks...

I've seen some dive and photo shops that rent entry-level underwater cameras at tourist destinations, that might be worth looking into. I don't think you'll see much of a difference between a disposable and the cameras you linked to. You might be able to find someone on eBay that is selling a used, inexpensive digicam + housing for a deal. If you go digital, at least you'll be able to take a lot of pictures without the worry of running out of film.

I think you will be disappointed with your results from these cheap disposables and 35mm models. My wife was with hers and switched to putting her digital into a Ewa Marine bag. The results were dramatically better. I know it is only a plastic bag and it is easy to scoff at them but they are very robust and well made. Many people use them for snorkelling without problems and they are also sold for shallow diving so snorkelling depths are well within their capabilities.
You would need their D-A model for your Canon S2 (my wife uses the same one for her Panasonic FZ5). I think the IS helps her significantly and you have that too.

Hope this helps

I agree with the Ewa Marine bg idea. Don't spend hundreds of dollars on a housing unless you're going to scuba, which in itself is pretty spendy. I'd recommend trying a bag or disposables this trip, see how you like it and make any big expense decisions after you've seen how much you like it.

Thanks for the responses everyone. I've emailed the Ewa Marine US distributor - hopefully I'll hear back soon. And I'll definitely look into rental possibilities - hadn't thought of that one.

Keith - I don't think I'd spend hundreds on a housing even if I were going to Scuba dive. I'd rather spend the hundreds on a better camera than my S2

For anyone who might be interested, Ewa Marine bags are available at Adorama. For the bag and adapters I need it's in the range of $250 - not nearly as cheap as I had hoped. I'm sure you get what you pay for, but I'm only looking to spend $100 or less. Looks like it's rentals or disposables for me.

I picked up a sony W7 DSC for which I have a sony marine pack housing (good to 40m) last week.
ideal for what your talking about, still a few hundred dollars but good for the kids at the beach or swimming hole...
