I'm running a 2M pair of Cardas Cross out of my Mac MC202 into my fully "gunned" MG12's. I like what I hear. I was running Cardas Quadlink 5C when the 12's were stock. You can pick up some good used buys on either of these to stay within your budget.
Shotgunned means you run (1) "stick" of wire, (usually one stick is both positive and negative) tied together, so you have one piece, (stick) of wire per positive and negative run. 4 total pieces of wire for a pair of speakers.
