Hi Mark,
The Makita is made by Husqvarna (still is I think) and these are probably (in there price range) the best saws. If not using heavy enough extension cords (minimum 10 ga) and no more than 50 feet of cord (25 much safer) the draw on these engines in constant use will burn them up quick I have found. Also not keeping them well lubricated (I use peanut oil or canola.)
As for "professional quality" yet still easy to find and get parts for...Stihl...is my third choice.
Hope that helps,
j
