+2 for a Husqvarna 372XP, but even with that said they are almost always "beat" by the time they hit the used market, and low hrs lightly used units bring nearly the price of a new one, so it's a lottery ticket to get one at a reasonable price.
Probably a more realistic and affordable choice would be a 268 or 272XP. They show up on occasion in decent shape and the asking prices are typically hundreds less than an equivalent 372XP. Very easy to work on as well, and no shortage of parts for them to date.
I saw someone recommend the larger Echo saws, and as much as I like a lot of their products, the larger offerings are heavy, lackluster in power output, and don't really sport "Professional" features. Specifically the CS-670, 6700, 800 and 8000. I've owned several samples of each, and sent them all down the road as they simply didn't make the grade. Completely different story with their new CS-590/600/600P/620P series. I recently acquired a CS-590 and a 600P, they as really nice saws for the money......Cliff
