Value of a Husqy 2100? I have a guy looking to trade that for my 660. I have no interest in the Husqy so I'd just turn around and sell it. Thinking it might be an easier sale.
Can be $450 to 700+ depending on appearance/condition/demand. Got mine April 2013 from retired Oregon timber cutter,excellent condition for $425 powerhead only to my door.Seller took $30 off since I already had several longer bars & didn't need the 36" .063 bar he had listed. Didnt need a thing done to it.All I did was retune the carb a little,it will need new gaskets etc in a year or so,that's a simple fix....
Good condition it can bring more to a collector than a 660 will. If you can get pictures of it the value can be guessed better.
TRADE your 660 NOW for that saw assuming his saw is not beat all to heck and has aftermarket Big bore or P/C on it!!!
If it's got a BB kit on it they spent some money to fit a 3120 top end or had it bored and replated. Either way they knew what they were doing and made a real strong saw with it.
Any pics? It can be worth more than your 660 in good condition? But it can also be worth much less if it's beat up. It's a much, much older saw. But as stated above, if in good shape? A collector will pay a premium.
