I think the new ones do sell for around 289 so 140 for a lightly used Powerbow is a fair price. Buy it if you like the feel of it. Personally, I much prefer the old PB shape. Good luck
Probably he got it from the old stock clearance.I have one GN Ignite 2009 I bought new couple of months ago.By the way what year did this model came in.2010-11? Here is the profile shot
You are LUCKY because many of our friends simply adore that old shape but unfortunately it is out of production. Like I said, 140 bucks for that is good as long as you are sure it is not too dry.
