I swapped a 2100 with a bad coil for a port job on my XPW, a 32" Stihl bar that needs a tip, and $2. I didn't really need to get rid of the 2100 and I didn't really need to get the W ported but since my buddy who builds hot saws is a 2100 nut I figured I might as well swap a saw I don't need for a port job I don't need. The $2 is because I didn't have the exact change for a parts deal, fyi. I also wet sanded a truck, returned a saw and a blower to a buddy, and picked up his 350 that I thought I'd fixed but is now acting like it has an air leak, again!
