Anyone still using Instamatic 126 cameras and film?

I know they may be too inconvenient anymore but I have seen where some people are reloading their cartridges with 35mm film.

Don't know if they qualify as "Toy Cameras" but I'm looking forward to playing with some old Instamatics once I can get them loaded up.

Anyway, if anyone knows of a low-cost and simple source of old 126 cartridges let me know. I'd like to find a few to try the 35mm thing and ebay people want insane prices for 20 year old film. It's a lot to pay just for a plastic cartridge.
