We occasionally use the IgniteNet Fusion Dishes with ePMPs when we need a few extra dB than what a Force 200 can do. There nice because they're a little smaller than most 30dbi dishes (there's not a flat edge around the outside, like most 2' dishes have), and they're cheap. They're not the easiest to assemble though.
