Been looking at a Masterbuilt myself, specifically the AJ500R, slope shouldered dreadnaught with Rosewood B/S. The couple of mahogany ones I've played are really nice and they're a great value, hard to find much that good at that price point. I have a couple of Recording Kings - a nice Adi-topped solid mahogany dread (RD-316) and a solid maple bodied L00 blues box (RNJ-25) that are fantastic guitars, but hard to find local dealers that carry them so you can play them. I also just bought a solid mahogany Eastman OM (AC-512M) that is the nicest guitar I've ever owned, but again, not a lot of dealers around that carry them. Buy most of my guitars online, but do a lot of research before pulling the trigger, definitely nicer when you can play the one your taking home!

Glad you found a good one, if you live in dry country like me (Colorado), be sure to keep it in a case and get a humidifier for it...my necks and tops can warp enough to get fret buzz in a week or so in the winter here.
