Right, there's no point in trying to get someone to switch to tubs if looks is what they're after. There's nothing wrong with going for looks..It is possible to manage temps and humidity in a tank..it just takes a little extra work, but it can be done...I know, i've done it before.

Having said that, It is not necessary to buy either a tank or a rack. There are some beautiful enclosures that hold temps and humidity quite well and are visually appealing.

Neil Golli used to sell some but i don't see them on his web site right now.

So, if you've already got the tank and want to go that route, then what was previously said by ddbjdealer should do the trick for you.
