I own both a 2003 Carbon Force Pro and a 4-runner Pro and haven't had a bit of trouble yet from them. I also get good customer relations, i.e. fast responses to various questions. I know the Co. is back under it's orginal President and he seems to be a quality stickler. If it's not a pre 2003 4-runner you should be just fine, as I think some of the previous issues were still being resolved in 2002. Of course some haven't never had any problems with them. Nice shooting bows with fairly good speed and low shock/vibration.
Good luck with it and enjoy.
