I saw a very nice one at The Bombay Company. Insanely expensive though! Of course it will go on sale at some point, but still, I think it was $600. That's Canadian, but even so, it's still too much to pay for something that size (and that quality. Trust me, I used to work there), so I wouldn't buy it. I think that someone on the orchids forum got two very nice Wardian Cases at Sam's Club. They were nice and big, and very cheap. You could also get one custom-made by your local stained-glass artist (no need to use stained glass though; it looks pretty, but only blocks light).

Hey,
At a risk of creating a rival, check out ebay. Type in "terrarium" in the search---great items, no bidders. All types of cases including gothic, big aquariums, books, you name it. If I had the money I'd be in heaven:) Good luck!!

I forgot about eBay! Do check them out, as someone on here got two very nice Wardian Cases on eBay. Shipping might be prohibitively expensive for a large case, but you never know!

I bought a beautiful terrarium/stand with levels similar to the one that the lady who had the orchids from Sams Club. I love it. I won it on Ebay with FREE shipping. Check out Ebay.

Definitely check out ebay.. below is the type that I and a few other people got at Sam's Club for $40-$50.. but they don't carry it anymore... so that leads to ebay... where they are making a nice return.. even when they have "free shipping"
