If you look on KS there are a few ads up for proven adults. One of the sellers I've heard good things about, the other I have no clue on. I'd call and see what they have to say. The prices are uber cheap for this time of year though so I'd definately ask good questions.
There was also a guy on there with WCs for 150 shipped but I don't remember if they were eating.
Good luck, though you realize you won't be able to breed this year because of quaranteening and things right? Well... possibly early next year I suppose....
I talk too much some times.
Toodles and good luck
