So I may be looking to sell my EXcal II, because I never use it it's 4 years old and has less the 30-40 hrs of use. I want to use the money to get a nox 800. I like getting in the water from time to time but I'm a dirt hunter by heart and I love my nox 600. So any advice on what I should ask for in price range for it. or a trade for a new 800.
