These aren't made anymore.
JLW might know where you could get a used one in good condition. I have one and, when the lids were lost (pretty sure they're in a wall in my house - long story), I couldn't even find a lid for one. Luckily my husband conspired with Josh and purchased a custom-cut one for my birthday. You might be able to get this kind of tank made custom, but it's unlikely you'll find one cheap. The lowest I've seen a used one go for is $250, and that's without lids and with some serious scratches. You're shopping for an antique at this point.
