Cheap Casserole dish suggestions

I was wondering if anyone had any suggestions for fairly cheap casserole dishes? So far I have only been using the aluminum tins every time I make a casserole (once or twice a week) and im starting to think a good sturdy casserole dish would be a wise investment.

I have heard mixed reviews about glass cookware and one of my biggest fears is having something shatter on me. Would it be better to get a metallic dish? What about glassware would I just have to be super careful? And how much has everyone else bought theirs for? I really dont want to spend a bunch of money on one if its just going to break on me.

Thanks in advance! :)
