Oops, popping in from a long time stalking this thread.
@MattsBettas, I've ordered my DS from Bettaakapes, and as someone very new to the importing venture he was very polite, honest, and very helpful. He answered all my questions within 24 hours of me sending them, and gave me all the info I needed and wanted to know.
I recently spoke with him about stock off of aquabid, and though he didn't have the male I was asking about any longer, he has offered to let me know if future spawns provide what I'm looking for.
From the conversations that I've had with him, I feel like he would happily do what he could to help you out.
I don't know if that helps, but I hope so.
