At a recent gun show, I came across a brand new bow. It is a Hoyt Vortec, the seller is looking for $100.00 . It is a 2001 and is brand new, never used. I do not know the # or draw length. I am thinking of getting it for my 28 yr. old son. Good price? can draw length be changed? parts avail.? It is a bare bow, it doesn't even have a nock on it. Thanks, Stu
