That's a VERY good deal. That one looks exactly the same as mine. It's actually 37G, but I too was told 39G buy my
LFS salesperson. Mine measures 30"x12"x22". It's a height stretched version of a 29g.
I would jump on that in a heartbeat. The only thing I regret about my tank, I should have looked for a used on to save some money. I know I spent about $500-$600 total for everything (rocks, heater, tank, stand, filter, decorations). I could of bought a very nice sized used tank for that much.
Check out my pictures so some of my tank. I have the black stand instead of the oak stand.
