I would take a look at the Martins. I have never shot one, but they look pretty sweet and are pretty nice from what I have read on here. Most of their newer models have fully adjustable cams by just loosening two screws. They are also DARN cheap. Brand new TR-1 for about $550. My dad got a used 2008 Firecat for only $265 off the classifieds. He hasn't shot it much, but I do know it is quiet as heck for having no silencers except the string stop. I don't know if there is a better, more adjustable bow out there for the money.
