Hmmm... I think I'm wrong about that, Al, disregard that post, I shoulda researched before I posted.
DS, the 260 is an excellent saw, the 260 pro has a decomp button that you will probably not need.
Also the 260 pro comes with heated grips ( handlebars, whatever you call them)
It's a great saw, I've had about 5 of them, the one I run now is 6 years old. Thats 6 years of cutting professionally. I use it for slashing and falling x-mas trees, which I cut 10-15000 of every year.
I should buy a new one, but I want to see how long I can make it go.
