I've bought 3 crested geckos from Tree Top Reptiles (formerly MK Jurassic, I think) and couldn't be happier with the transactions, the customer service or the geckos themselves! The geckos are all well handled, and readily accept live food. Two were produced by TTR themselves and the other purchased gecko was from Pangea Reptile. I can't wait to integrate them into my own breeding projects!
TTR has great prices, very healthy reptiles, are prompt in answering emails and very helpful when asked questions. They don't hoard knowledge and are a credit to the reptile community here in Northern Colorado/Wyoming. I highly recommend doing business with them if you're in the market for some giant geckos or mantis!
