I have an Echo 260 with the saw blade brush cutter attachment and a smaller one for weed whacking, I also have a cute little saw that is about as good as the big boys on medium sized logs. The only problem I have with them is they absolutly suck in cold weather I'm not sure if it's the speed sensing carb or what but all of them stink in cold weather.
I forgot about an echo blower as well and it's proved to be reliable, except in cold weather.
As most here know I'm a developer so we do lots of tree and brush clearing. Some of our workers use Craftsman saws which I'm told are Echo and for $199.00 I think they are as good as any.
Personally I like Stihl because of the nice hats, shirts and gloves that the dealer gives me.
For us ol folks you have to try out the Stihl ms270c with the tooless bar system and split engine/handle design vibration is a thing of the past.
Cap'n tell us about the poulan from walmart
