I don't know if this qualifies as a you suck or not, but I turned a craftsman top handle saw exactly like the one pictured..
Into this...
The top handle and I went on a 250 mile road trip to straight trade for a box of three ms660's and a ms460. All were tarred and dipped in fir bark dust and ugly as hell. The owner traded work for the pile and didn't have any need for it, so he listed them on Craigslist for trade. The pictures were out of focus and I was barely able to make out a good Husqvarna bar and I recognized one carcass to be a 660 case. I sent a message with pics of my craftsman and he was all over it. Normally I wouldn't have taken this risk of driving that far for junk, but it was near one of my favorite fishing stops on the coast so I figured it was a win win.
So..one 660 was a runner out of the box with a broken clutch, two were missing top ends, and the 460 has bad bearings.
I traded the well used runner and this fresh build that I put together from those parts for the 880...which is brand new and has literally only made three cuts. I'm sick to see the 660 go because I built that thing to cut with an 880. Now I need to build another and try to keep it.
