It would depend on several factors, including the health and condition of the snake, its color and pattern(not all Guyana Boas are all that pretty), its disposition, and age. A lot of recent imports are available fairly cheap, but are often in bad shape, ridden with parasites, and have a nasty disposition. Wild-caught adult Bcc's are usually a lot more aggressive than the typical Colombian Boa, and they can be difficult to acclimate. IF the snake is cb, or long-term captive, and is in good physical shape, not too old, and feeds good on f/t, it would be a bargain, but I think the term "caveat emptor" applies here.I can get a 6 foot one for $80.00 Is that good for one of these?
