I've had many good dealings with Scales N' Tails over the years. They're one of my favorite pet shops, and they have a massive selection of tarantulas. I've bought most of my recent additions there. Animals are well kept, correctly labeled, and the staff is (with a few exceptions) well informed in both reptiles and invertebrates. They're prices are pretty standard, not top market but not ludicrous either. Then again, you don't pay shipping when buying from a pet shop. I would definitely recommend anyone in the Denver area stop by and check the shop out!
