The chameleon fabrics load two vest is probably the most cost effective way to get into a complete (or nearly complete depending on the matches you shoot) load 2 setup. I also think it is the best solution for load 2. It can take a long time to get it if you don't pay for express shipping.
I'm using the chameleon vest and AP Custom quad loads from the belt. If you are going to go with load 2, I wasn't very impressed with Taccom's offering. Their quad load is nicer, but still not as good as AP or Carbon Arms.
