I own a troy bilt and it great. I think the most important thing is to purchase one with a Honda engine. Seems you are already aware of that. Just look at what kind of psi you want and make sure its a honda engine and all should be good. Another thing to look at is does it use different tips...
Festool does make some badazz s***.
I have and use several of their woodworking tools and have been uber impressed.
Just don't have the $$ to always buy their stuff.
