I tried a bunch of em a while back. I previously owned the Milwaukee, then switched over to the Ego for a while, then back to the Milwaukee. Both are really good, but I just liked the Milwaukee a little better for what I do (and I still had Milwaukee everything else).
@Jody Treadway bought the Ego saw from me. The internet raved about the Echo battery chainsaw, but I personally found the trigger delay dang near dangerous. I tried to get used to it, and finally just took it back to the store.
I've also read about a lot of people loving the Milwaukee Hatchet pruning saw, which might be right up your alley if you're not doing bigger stuff.
