If you want tiny, there's the recently released Echo 2511P and the more expensive Stihl MS 151. If you need more power you could step up to the Echo 361P, or the rear-handled version of the Stihl 201 if cost is no object. The small Makita's get great reviews also and are less expensive. I assume there's a rear-handled version of the Stihl 193, though the 2511P probably has almost as much power in a much lighter package, and the 361P will cut circles around it for an extra 1/2# weight. The biq question is - what are you going to cut? If a 12" bar is all I needed, my pick would be the 2511P (I have the top handled 2511T and love it.) Another option would be to wait for the little battery Echo that's similar in weight but hasn't made it to the states yet.
