Thanks!

I rather like the 36X18X18. Haven't priced it - probably a few hundred dollars each with shipping.
Something to budget for for next year.

I already have a yard sale tank that is, IIRC, approx. 12WX30LX20?H. Heavy and cumbersome, but has potential to be pretty if planted well. It is so tall, it will need a low (and sturdy) stand if I ever do choose to use it.
