Those saws sold new at the dealer for 750 to 800. The muffler is going to cost 60 to 75 to replace. Like has already been posted, Id say around 300 with a new muffler would be a fair price. Unlike most on here, Ive used the 575 and 576 series saws a LOT in the last several years and I like them better than the 372 everybody around here loves so much. In fact Im still running 4 of them, albeit not as much as I used to. Ive switched most of my cutting duties to a 562xp for 20" stuff and a 390xp for the longer bars. AINT NOTHING WRONG WITH A 575 THOUGH!
