Good thread. I have 3 chainsaws and a brush saw; but have been thinking about an electric saw for some time. It would be nice to carry in the cab of the truck for when I encounter a tree across the road. In the time it takes to warm my gas saw up the tree can be gone, or any other small job which doesn't involve a lot of cutting. I've been eyeing the Echo CDS-5000, it has an 18" 3/8 chain and the same 5 year warrantee as all of my gas Echo products.
Just a word of caution though; while I won't run a saw without safety chaps, an electric has enough torque to cut right through them.
