Just ordered a new Omega 75cf tank

"Tominco"I made my own base using scrap 2x6's and some velcro. I ended up with a nice little bonus shelf underneath the bottle that held pellet tins. 
I'll see if I can post up a pic later on.

There are commercially available bases. Check with the big names like AoA, precision, Joe B. One of those guys should be able to help you out.

Thanks! I'm not the handiest guy when it comes to carpentry but I bet I could manage a simple frame. I'd love a pic if you find one sometime. Thanks!
