Pretty happy with the 2 Echo`s i bought. One is the CS-4910-18, the other one is the CS-7310P-20. Both are great saws, in my own opinion. Lots of them where i live. People love the dependability of the Echo brand.
If you want a good dependable 50cc pro saw, go find a CS-4910 before they are gone. The new version, the CS-4920 is not a pro saw, its a homeowner saw now. If you want a little better one than the CS-4910, buy a CS-501P. The 501P is a great saw, with a few minor upgrades that are worth the extra money. The 501P is pretty much the same saw as the CS-4910, with a few added features vs the CS-4910. The CS-4910 use to be the affordable entry level pro saw. Pretty sad Echo stopped making the 4910 and started pushing the 4920 to homeowners.
I use to be a hardcore Stihl guy, but i no longer am after buying my 2 Echo`s. They start great every time. I can depend on them, without emptying my wallet.
Husqvarna saws aren`t popular where i live. Mainly i live in Stihl territory. I`ve never been impressed with Husqvarna`s, they look like cheap quality to me.
Another thing i`m not fond of, is every time i go look at a husky, there`s always a new model(s) way to often.
