K, just to update. I decided to go with the kobalt 80v Max line. Close it because of the power available and cost. Identical to the greenworks stuff by the way and can use either battery with some minor modification. The kobalt is cheaper, easily available at Lowe's.
Haven't bought much yet, just the string trimmer. Battery charged fully in about 25 minutes and has way more perpo than it old black and Decker. So far I am VERY pleased with this. I also have a pole saw attachment for it, but haven't got to try it yet.
I had to use the mower a bit today and my darn gas can pump broke, so now I have probably 7 or 8 gallons stuck in there... I'm so done with gas!
