I thought $46 was pretty cheap for enough plywood to build a 2 x 2 x 4 Boa condo. LOL
[cheaper than solid wood, by far]
Home Depot is the only place around here that sells 4' x 8' sheets of Melamine particle board but it costs as much as the ply and the edges are always chipped and ragged.
I found a local place that sells sheets of PVC and am going to call Monday to price 2x4 sheets for flooring.
Does the PVC outgas when warm?
My enclosures have a false floor with heat cable running underneath it and I have to worry about that.
