1. largest breed is the scrub (not cheapest) Coastal is cheap and has quite a size
2. diamond needs basking spot of 28-32 degree (not sure about jungles) and UV
3.largest non snappy snake would be the olive
4.easiest to breed are macs (but costals for a bigger snake)
5.any of the antaresia group are "easy to keep" (again costals if wanting a big snake)
6.heaps

(bout 7000 was the last on on herptrader, not readily availible, the red ones that is)
7.a dark diamond can be quite black
8.clcik clacks are best for hatchies

hope that helps!
