Myka, I know I'm starting to sound like a broken record but build them yourself. I spent 3 years looking for the perfect tank that would work under my stand and finally bit the bullet and tried making one out of Acrylic. I couldn't believe how easy it was and I was easily able to create what I had envisioned. I got the acrylic cut at a glass shop (mainly because I have no power tools), and borrowed a router and those were the only power tools needed. In all it cost just under $200 to create the perfect tank. I'm sure someone with the skills to build their own stand can easily make tanks to fit your needs
.
At least keep it in mind for the future....
Good Thread so far, but needs more PICS!
