This has been asked a million times i'm sure, but I can just pick up a tub with a top on it at walmart or something, and use that to house my ball python right?

I want to get a spider, but don't want to spend a ton of money on the setup like I did on Vincent. Also, I don't have a rack, but it should be ok on my bedstand if I get enough room for the UTH heat to escape right?
