RE: checkmate hunter ll vs falcon
They have a different feel--the grip feels different, the Hunter II is heavier in mass weight--but they shoot similar.
You would probably do better to sell out-right rather than trade--I agree with Arthur on the resale value. I haven't done a lot of trading in the last few years, but with the little bit I've done you can generally expect a 25% to 50% loss on the original cost, depending on the condition, weight, woods, etc. My advice is start your price a bit higher than what you will take--you can always barter down.
