I haven't put the 550xp into wood yet.
The 550xp specs are very similar to my Dolmar 5100s....and I love my 5100s
I have a 572xp, so I am familiar with the AutoTune
Yea, the sale price with $140 off is what made the sale for me.
In December the dealer had a couple ms261's in stock, but the Stihl sale included a carry case, extra chain and free hat......No money off, really didn't move me enough to purchase one. I don't use the carry cases I already have, I have plenty of bars and chains for my ms270 that would fit a ms261 and I have a couple dozen Hats.....Cash off did the trick.
