Well honestly, I'd have to vote for T.c.ocellatus. There's really nothing out there like them, everytime I see them I think..."Damn I've got to get me a pair of them!!!"

Unfortunately, everyone I know who used to work with them (in my area) does not anymore. Besides them.....and of course T.radix, my biggy to find would be a pair of T.e.terrestris...but I'm thinking that might not happen....I've NEVER seen them anywhere. Well except for Alan Francis (and he got rid of his) and of course Gijs and Sabine's, but I'm on the wrong side of the pond for them.
