magiriano, just wondering, have you ever used a saw with a heated handle, like the xpg? Are you sure that you really have a need for one? My Stihl 038 has one, but even in the cold conditions I sometimes work in, having one hand stay relatively warm only when running the saw, it doesn't seem to be all that purposeful, and you also pay more for the privilege. I'm sure that there are varied opinions about it, and I don't mean to dissuade you, but maybe just save you the trouble of finding a dealer if you don't really need the option.
Good luck with whatever you do get!
