Interesting topic !
I agree with Cameron ... and I agree with Dimitri ....
You can't really separate the topic on pricing of rare T's from the importing of rare T's... The one hand washes the other.
So, don't be so defensive ... If you are publicly going to boast about having recently imported tarantulas in your collection, be prepared to receive some public flack and scrutiny .. not because everyone is necessarily walking the straight and narrow route, but because it is wrong, no way to argue out of that. In Afrikaans they have a saying: "Die deler is net so goed soos die steler", so when buying tarantulas from these importers, you are helping them to break the law. Now I'm not saying buy imported T's or don't buy imported T's, but South Africans in general don't have a very good reputation in the outside tarantula world, as we have no problem breaking the law to make a little money. I see this on the Facebook groups (Local & International) every day. And I think a forum like this should strive to live and breathe the letter of our country's law - whether or not everybody agrees with that law.
Regarding the pricing - it's not really going to be something set in stone - The first person to import and/or breed with the imports will make the most money, so that person will set the price. From there, as the supply grows.. the price will start to fall.... either gradually or very steep. There is only one person I know that can slap a 100% markup on T's and still get away with it! (check Gumtree if you don't believe me).
You can't really use overseas prices, as they have a different supply/demand chain in the hobby. And as Dimitri mentioned: What makes these rare T's so special? Is the attraction towards the tarantula .... or the price (i.e. somebody slaps a price on it and makes you think 'hell, that T is expensive, so it must be special, I need to own it now!')? Some of the most interesting tarantulas are the cheap ones!
If you REALLY want to compare prices, rather visit Tarantulacafe or contact Hendrik directly - he has always been very fair when it comes to pricing!
@ Dimitri - It would be nice to see the REAL interest in the hobby if you take away the pricing, I'd bet on a 80% fall in number of keepers !
