....Or if you have money (and bad at making things like me), go to a good petstore and they should be able to make you one. Thats what I did. I saved a few hundred because the glass they used was 6 mm thick not 8mm thick (They used 8 mm on the base, 8 mm is used for aquariums but 6 is good because there is not much pressure on the walls).
I said what I wanted and they made it! But I dont know what kind of pet stores you have in america, where im from we only have local ones no big multibranched petstores so their willing to do this.
