Where can I find quality knockoff kits?

I have kids playing in the Mexican leagues cuz the white boys play way too soft. It's time for new kits, and the usual supplier has become unreliable. I want to find the kids good kits, but the families are immigrants and don't have cash to burn. I've seen a thread on here a long time ago about a good source for great quality knockoff jerseys. Can someone point me in the right direction? I want to get them full kits, at least jersey and shorts.

TIA
