Thanks for all the comments and links everyone has posted. I did a little research and ordered a couple of the pyrex mini protank 2. They look pretty and now I don't have to worry.
I'm a little disappointed with the local vapeshop, because they really didn't inform me of the polycarbonate melting/cracking, etc.
I realize this isn't a new topic for a lot of you pros, but was wondering how common this actually happens. Judging from the responses to my post, it happens a lot more than I initially thought... Which was that maybe it was a fluke of nature type of thing. But I guess it's pretty common.
Whew, glad I got my glass tanks
