I had a great Dolmar dealer. I bought two 5100's and two 5105's from him. I really wish I had bought a 6400. I was able to use the saws for 2 years and sell them for what I had into them. Eight years of free saws, hard to beat.
Makita made a mess of Dolmar so I started buying Echo. I picked up a Echo cs400. Really nice little saw. Used it for 2 1/2 years and sold it for $100 less than what I bought it for. I picked up a Shindaiwa 402 (same saw but all red). I would love a Echo 590 Timber Wolf. If I get a tree removal job, I will buy one.
Really happy with my Echo, Shindaiwa, Kubota dealer.
