For the more expensive finches, a lot of them are sold thru bird marts and fairs, swapped with other breeders, or posted on some of the online sites for selling finches.
When I decided to go all out and try breeding on a bigger scale, I started with Stars, then Gouldians, then got into waxbills, and the waxbills really intrigue me. I believe there is a market out there for waxbills, but even if there wasn't, I would keep them.
But this is something each one of us has to think about before we breed our birds. Craigslist and Petfinder.com always have Zebras and Societies for adoption--sometimes I see the same birds posted over and over. So before breeding birds, try to decide what you will do with them once the two pairs have multiplied to 20-30 birds. You will need more cages, you may have to separate juvies by sex (my Star juvie boys are flirting with their sisters), they all really shouldn't be sold till they've gone thru their juvie molt. You are looking at a commitment of time and money, not to mention the space all those cages take up!
There is nothing wrong with keeping finches and NOT breeding them. But if you are fascinated with the breeding end of it, as I am, then go for it, just do a little homework before things get out of control.
And I will be at the Ft. Worth Bird Mart in September as a vendor!
