Something cheaper?

I then thought that working on my holga for this project would be out of my price range because of the cost of both film and development! i went on to ebay and managed to pick up an old film slr a Canon600 howver when the camera arrived it came with no manual and i seem un able to find much on the internet about this camera, not only this but the seller promised to send me a battery and did'nt so i had to order from and ebay seller in europe just to get the battery! when i began to scroll the internet i couldnt seem to find anything about how to work this camera and since film wise i am not familiar with to many film camera's other than a pentax k1000 and a praktica LTL3 i couldnt really figure this one out myself! i tryed to experiment with it however the film came out blank so either the camera is broken or i did something very wrong... i have left this camera to sit on my shelf until i can figure it out!
