I've had the Fm3 for almost 2 months and I'm loving the sounds (and uprade from the Helix floor for me). I purchased the Morningstar MC6 to control it initially, then last week I impluse purchased and FC6. The OMG9 setup is nice, and it's great to have the units looking the same, however, I'm not sure the FC6 is worth the huge price. Feel free to convince me i'm wrong, but at a little over $200 for the MC6 can do most things. I'll admit, the switch spacing and the larger display on the FC6 is nice. Anyone used both of these?
