all the candoia except asper (already have asper)
mandarin rat snakes (Elaphe mandarina)
Chinese Beauty Snakes (Elaphe taeniura)

Sumatran Black Blood Pythons
0.1 Sumatran Red Blood Python
1.0 Guyan BCC

Lots and lots of corn morphs, lavender, snow, amel, anery, motley. sunglow.
0.1 frosted cremesicle.
brazilian rainbow boas (actually i want peruvian but they're not likely to be in my price range anytime soon)
Black Mexican kings
Stuff I'd like but I'm not ready for right now.
Yangtze Habu (Agkistrodon blomhoffi)
Sulcutta Tortoise (I don't think we'll ever have the room for one of these, never mind a breeding pair).
Galapogas Tortoise (Same as the Sulcutta and then there's the CITES restrictions)

There's more but they slip my mind right now
