Alright... so I went and took the 90 he had right there in the store today.
No, there were no back room deals. This is why I like this particular dealer... I walk in "Hey Jim, I like the FS90."
"Ok Marc. Do you want to buy it?"
"Yup."
"Ok, let's put some gas in and make sure she runs."
Hands it over with display shoulder strap attached. Says nothing so apparently it was part of the deal for 299.99.
I'll use it tomorrow for the first time. I was too busy today burying the nose of my 290 in some downed 36" DBH sugar maple I scored on the side of the road... about a cord's worth, maybe more. I'll take pic's of that when I go back. I'm getting a bad case of the CAS. I'm wishing I had a 7900, 460 or 575xp about now... I may be rectifying that situation soon...
Oh, he threw in the mounting hardware for the four sided grass blades I already had someone gave to me... so all in all, a great experience.
