Yeeeah.... Considering that darn ibd thing, I would have to agree with this. I do believe that ibd is somewhat blown out of proportion now and isn't something to be necessarily paranoid about, but it does pay to be careful - very careful - when buying boas. Even if you only have 1 other snake, it would be tragic if it died because your boa brought something into the house. There's another thread regarding this in this same forum you might want to check out, but basically, if you're going to buy a boa, get a baby (babies don't incubate the virus nearly as long) and buy from a reputable breeder only. Just my .02....
Incidentally, Tim at Special K had some very nice "normal" babies for about $30-40. I don't intend to "push" a particular breeder. I am sure there are other great breeders here who have some good babies available. But since I just worked with Tim myself, I happened to take note of some other things he had. Might be worth checking with him....
