Wanted: 100 Gallon or Larger

[Seriak]

I am looking at adding a sump in my basement and was going to go with a rubbermaid style sump. Unfortunately, the bulging problem of the inexpensive ones limits my baffling ideas. Anyone have a large empty tank that I can convert into a sump in my basement. I am not looking at spending a lot of money, please keep that in mind!
