Well, I wouldn't say melamine is as bad as everyone says. Yes, it's heavy and not the most attractive, but I've had no issues with cracking.
Plus, it's very easy clean up and I don't have to worry about toxic varnish, stains, etc. And it was super easy to work with (cutting, assembling, etc.)
I agree it's not as warm (visually) as dark wood, but I still think they turned out OK: http://jodyberry.smugmug.com/Vivarium/Vivarium/15140299_RNgEn#1137740208_dWTgh
