There is a guy on eBay selling NEW IN BOX '08 Ross Cardiacs (pre Bowtech ownership). Price is $425 OBO. I just bought one for best offer price of $375. I think these bows used to retail for $650-$700. Just received it and it is a great bow. The quality and finish look top notch. I would highly recommend.
You can also find new PSE Mach X bows for $375 on eBay right now. They used to retail for over $699 I believe. I don't know much about them, but they appear to be nice bows. Just some suggestions for you. Otherwise, check the
www.archerytalk.com classifieds. They alwayshave a ton of great deals on there. A lot more selection than on here.
