I have a low hour all original 7900 . Probably around 10 tanks total ran through it. Would like to sell it with all the bars and chains for the saw. Currently has a 24 inch like new Oregon bar. I also have a 20 inch Total and a like new 28 inch Power Match I'm guessing I have a dozen chains around for it. All like new. I haven't been cutting much in last several years and my next biggest saw is an Echo and it's been doing just fine for what I need. I'm in the Pittsburgh area.
