Bow looks to be in great condition. It's 2005 I think and doesn't come with any accessories. It's the monocam model, not the hybrid. 7mag's in pretty good condition. Weatherby van synthetic. Nothing fancy.
No way would I do that trade, not without some cash.
Bows are not like guns, they do not hold their price like guns. Most of the time, I figure most bows are worth half what they were new after 3 or 4 years. Some of the top of the line bows, hold their value a little better, but not much more.
