the alligiance is a great bow,the sportsmans wharehouse that I have service my bows swaped out the cams on my old glory for free,they have these cams on a shelf and if they take an e7 off and put an e9 on they still have the cams for someone else as opposed to making a person buy a set every time you change.I dont know if every shop will do this maybe were just lucky around here but the fact that they tune,install parts that I dont buy there,serve the string when it needs it,let me use the chrono and shoot in the store whenever I want,comes back to them when I refer all my friends and relatives to them.Find a good shop like this.as for the price,600 is not a steel for an 05.I baught my 05 old glory this summer for 375 brand new,never shot,with the hat,birth cirtificate,manual,warranty card,the works.I baught my 04 black knight for 3d tournys for 350 a year ago,I will never buy anything but a bowtech but I also will not pay 729 for an 06 old glory like my cousin did 2 months ago
