Went to my local martin dealer ( for now ) who will be droping the line as of this year. He has two ryteras that are new 2010's, one an alien x and a nemesis. I was actually looking for a black bow and both of these were camo but if a good deal I would get over it. I wasn't thrilled with the alien's grip. Could see serious finger damage happening. Anyway, he said he would let either one go for 550. Don't know if this is a good price for these or not. What do you guys think? I tryed going around online looking for prices but was only able to find used bows. As I was looking at some of the bows I was reading about an upgrade for cams for the rytera's. They are called elite envy cams. Where did these come from? Are they something you can order from martin direct? What is the reason for this cam change? Anyway, was thinking about maybe adding on but would like to be alittle more educated about these before I spend alot of money. thanks guys.
