Yeah there are tons of great ones out there, though not all will have what you're looking for. Here's some off the top of my head in the US:
Morelia Trophy Club (John Battaglia)
Peterson Reptiles
Headhunter Reptiles
Reptilicus/Spectacular Carpet Pythons (Will Leary)
Inland Reptile (Nick Mutton)
Australian Addiction Reptiles
CBReptiles
East Coast Serpents (Jason Baylin)
ReptilesByAH (Andrew Hare)
Spitfire Reptiles (Yasser Moustafa)
That'll get you started. There's more out there that are great, but those are the ones that come to my mind immediately. Moreliapythons.com is a great website, and many of the members there breed but don't run businesses or have websites, so it's worth keeping an eye out. Also I've found a few guys on iHerp have amazing specimens, and plan on messaging a few of them inquiring about future clutches when I have the ability to add more animals to my collection.
I put names down to go with them when I remember them correctly![]()
