If the first guy is actually showing interest in YOUR breeding projects, to me, he's got some great customer service skills. He sounds like he knows his stuff and he's willing to work with you on your budget and with your breeding projects in mind! I would choose him first, then the second one. Even thought he second one has a great reputation, I think superior customer service trumps reputation (granted...this is not the case if the seller clearly has bad reviews).

It sounds like you know who you want to pick! Just be confident in your purchase. I'm sure the female you end up getting will be beautiful!
