I do not know if my method is the best or not but this is what I did just recently as I had exactly the same thing happen, allthough I did get some bad mice that wiped out half my colonies.
I too have local stores that seem to have only one sex in stock, so I got 3 males from one store, 6 females from the other and started 3 lots of 1:2 colonies. I let them go for a month to see which ones were showing signs of reproducing and then fed off the seemingly slow starters (who knows if they would ever breed). Once I got babies from the good breeders I kept a few back that will replace the once recently fed off. (my theory is that they came from good breeders, so why won't they be as well).
This way will take a little longer to get a healthy, established few colonies so buying frozen feeders is still a necessity for a while, but the path is layed down so to speak.
The main reason I am producing my own is to have live pinkies on hand for those problem starters, or to "kick start" anyone that may go off their feed. Economically it works out pretty much the same when doing it in relatively small lots (say 3 or 4 colonies) as buying in F/T.
