I've been wanting one for some time now and finally decided to take the plunge. I was going to go with a Mexican red knee and I saw a 4"er at a shop, but I needed to set up the enclosure first and didn't feel like driving up to Fort Collins to get it, so I went to Scales-N-Tales in Englewood and picked up an ~5" "metallic" pinktoe. They had a red knee there, too, but it was less than 2 inches and I don't have that kind of patience. I know it's more arboreal, but it should be fine in its 10 gallon tank, although I do need to add more decor. Right now, it's @ 79 degrees and around 71% humidity, so I may put a little glass over the lid to trap some more moisture to increase the humidity, but I realize this species needs good ventilation. I'm already anxious to get my next tarantula, which I'm thinking about maybe a suntiger, but I want to gain some experience first. I really like the cobalt blues, so I'd like to get one fo those eventually.
