$200 for a 6" doesn't seem that bad...they're kind of out of season now though, so that one may have been sitting at the LFS for awhile. You could probably find one online for $100-$150, but you're going to end up paying at least $50 shipping, and if it dies the next day, you're out your money. At least you could take it back to the LFS.
I've been eyeballing one of these too, but I'll just wait until the babies are plentiful again next year and cheaper.
