For a pro, or "nearly pro" I can see not waiting on parts, gotta get the saw going again asap. But for the OP I don't think that's a priority. However, if he can't do his own work then he most definitely needs a servicing dealer nearby.
I think no matter what you run, you need to have a back up.
My main saw is a Dolmar, but I have a back up Husqvarna 395xp.
And if need be I have a few other Huskies and a Stihl or two ready to go.
