Thanks guys! I am really happy with the way it turned out too, if you want to see a few pictures of the process you can see it here:
Retro-fitting a few more horizontal perches would be easy... plus if I went with an arboreal snake I would probably want to make sure they are removable too!
Unfortunately I live in Canada and LLL won't ship here, so finding anything even slightly rare is tough and/or expensive! The only gtp hatchlings I have found were over $800

which I thought was a bit high! I'll find something eventually! I'm really hoping our local expo in two weeks brings in more than just cresties and leopard geckos lol
