Well there's really no price comparison for this project, cuz it's fitting in an alcove in a room we have. It's 66"wide 24" deep, and 36" tall. It won't save me a TON of money, I think the stand and aquarium materials (plywood) cost me around $275CDN, or $225USD. The glass will be $250CDN, but it's 5/8" glass... I could have got 1/2" for about half that.
The epoxy for sealing it was given to me by a co-worker, so that will be free, and I'm not counting tools in the total cost, cuz I had most of them already.
