planet aquariums is down in TX not sure where but most LFS seem to get em.
I am in the same boat looking for a 300. but I live in the one light town pop. about 2,226 people so I think you have better luck finding one local than I do...lol
in all seriousness planet or glass cages if you want glass. if acrylic the prices from acrylic creations seem reasonable.
good luck!
I bought a Planet 270g earlier this year and I don't think I would buy from them again. The tank its self is fine, but Planet/DFW has been kind of a pain to work with. I still have an issue with the overflow lids that they are just ignoring at this point.
