IMO I'd consider it at $600. I've been out of the market for a long time so things may have changed. My take, it's an 8 yr old bow model that was well spoke of in it's release date. In the past, last yr bow models would be worth 50-60% of new purchase price. One might only be able to give away an 8 yr old model? Arrows and other accessories don't usually add much to the price of the bow, though perhaps they should. Also, if strings and cables are more than 1 or 2 yr old you would likely want/need to have them replaced, probably $100+.
How I came up with my price:
Bear Arena 34 - $250
Releases - $60
Arrows - $20
Target -$25
Stand -$150
Sights/Case -$100
Total -$605
then again, I might be off on depreciation these days and the longevity of strings and cables? Hopefully someone with more up to date knowledge will chime in on it?
