Agree with Morph Market, just be careful about ratings and make sure and don't pay "friends and family" method of paypal - pay the normal transaction way.
I've personally had great experiences with these sellers on MM:
MB Exotics
Morton Wright Reptiles
Maryland Ball Pythons and Exotics, LLC
Regius Creations
J & Z's Exotics
Morphmart Reptiles LLC
Strictly Reptiles, Inc
Leftside Reptiles
Kelcifers dragons
Dynasty Reptiles
and Herpetofauna Company (idk if they do BPs)
I've also dealt with many great breeders outside of MM over the years but the only ones I know of that are still around are:
JKR (forget what the new name is but he rebranded recently)
JD Constrictors
Mike Wilbanks
*I believe all three of them have Morph Market accounts these days
