Any model Echo or Stihl would be quite an upgrade from the Craftsman. The 290 "FarmBoss" has a sub $300 price and is very reliable. My 280 was around $450 two years ago and it's a pretty tough saw.

/ Chainsaw not Starting... Craftsman 46cc 20" used once.
I just bought a used one of the same brand. Mine started alternately running GREAT and then dying and hard-starting. I found the fuel line (draw) was breaking off because it was corroded. Once replace, the saw ran like a champ again.
