Most counter tops and cabinets in your home are made from particle board. The best place to buy your melamine is from a mill shop or a custom cabinet shop. Tell them what your are using it for and the specifications and they will get you the right stuff. I can build two 10-space racks for less than what most cage builders charge for one 5- space rack.

As for sagging, I've seen more sagging in plastic caging than any other type.
If I'm buying 4x8 melamine sheets what should I be looking for to ensure I'm getting the best material I can get for my $?
