I knew one friend was looking for a 2101XP, and another was looking for a 390XP. I found this seller who had both. Turns out, he also had the 372XPG posted. I was able to scoot up from Western MA and grab all three saws and some sweet sweet ethanol free pump with the buyer of the 2101XP.
The XPG and 390 have chainsawpipes.com pipes on them. Louder than what I'd normally want, definitely cool but not friendly for the neighbors, so the pipe might get moved to my 372XPW so I can enjoy the XPG more frequently. I'll add some family pics later bar'd up as I feel I now have the OE trifecta: 372XPG, 372XPW, and Jonsered 2171 all in good to great shape.
