i know a lot of people that use the wal-mart sterilite tubs. when you go to make holes in the lid, (which is very secure and i never had a snake escape) be VERY careful if you are going to drill holes. i broke two lids trying to drill holes. the plastic on the lids are very quick to shatter and crack. i saw on this forum AFTER i did that about a guy having the same problem. he said he was very successful using a soldering gun and melting little holes in the lid. this worked like a charm. if you must drill holes, use a piece of wood under the lid as a backer and BE CAREFUL.
Yea, definitely buy a soldering iron. Makes the job a lot easier and not nearly as messy. You can get one from your local auto parts store for like 6 bucks.
