The "farm raised" BTs they sell are imports, why do you think they show up the same time every year? Can you say WC. When Pro Exotics sold a CBB BT a few years ago they were sold for $225-$250 plus each, the imports are $165-$185 plus, ask Robyn yourself, if he sells you a CBB monitor he will also tell you how old it is, who bred it, etc. Pro Exotics produced CBB BTs in 2002, since then I havent heard anything about any more being hatched. If someone sold you a BT that they say is CBB for $125, they sold you an import they bought really cheap and wanted to sell fast, not many BT or WTs in this country in the last years that are CBB. Pro Exotics had at one time Faust crosses, I havent heard of any available there since.
By the way argus grow to 3.5-5ft depends on sex (males are much much larger). BTs can grow 5-7ft plus (again depends on sex). Argus are a medium size monitor, BTs are a large species. There are many many differences between the 2 species, too many to list. Argus are on average less expensive CBB, as they have been bred alot longer in captivity, as well a whole heck of alot more often, very regularly actually. About the only species that sells for less than $185 each CBB (argus) are yellow ackies, most are $300-$1000 plus.
