I just bought a stihl 028 AV Super couple weeks ago,it was used in good condition and ive been using it about every other day because of the ice storm we had, and I have not had one problem w/ it yet..
The guy that sold it to me said he thought it was about a 10 yr old model.
I gave $200 for it and a new one was over$400. I bought mine at auction online. Good solid chainsaw!!!!!
