I pulled the trigger on a Royal 800 on Ebay 2 days ago. Looking today there was a newly listed Black Max 5.3...snagged that one too. So I'll have a 950, 800, and a 5.3 for my IDX. My buddy apparently has a 4" Blue Max that he got at an estate sale that I can trade him out of. I think I'm all set in the coil department!
