Yeah I went to a reptile expo last year to check out the ball pythonsand other reptiles they all looked very healthy and good prices though right now I can't get one due to my brothers wedding, but after that I'm thinking of picking up either a pieball, axanthic, mojave, or just normal one it depends on the one I like best when I go to the expo again luckily I have a spare 10 gal tank and a 20 gal for later just need to buy a couple hides, water dish, UTH, and substrate..
I agree about not going to chain petstores I haven't set my foot in one in 4 years ones I've been to in the past their snakes and reptiles just don't look good luckily there's a pet store that takes decent care of the snakes and feeder mice though it takes 30 or more minutes to get there depending on traffic I rather support them than going to the local petco..
