So my boyfriend got a bonus check from work and we were planning on using the money to build a rack. We're not sure of number of tubs or anything yet, we haven't gotten that far. But we can't get expanded PVC there (the money has to be used at the store he works at) and we've already ruled out Melamine due to the weight. Well, not completely but we want to avoid it.

I'd be super interested to hear of anything other than PVC or Melamine to build a rack out of and also see it.
