Welp, went with a 2 stroke echo. Talked to a couple people who have battery trimmers and then talked to a dealer. The big kicker was, when the dealer had some battery ones, but didn't want to sell them to me and he told me the background. I was looking at Toro. Apparently Toro and a couple other higher end brands he sold have changed designs and batteries every two years. He said he has last years models, but nothing will work with this years, and his won't work with anything over 3 years old.
So I said screw it and went back to 2 stroke instead of 4 and went Echo.
