I have a EGO single stage with two 5.0ah batteries. This is my third year with it now and it's been great. A couple of minor battery issues but nothing overly concerning at this point. I also have the setup for the pull saw and tiller along with the 620cfm blower. It's been great! No fuel to store or mix, no storing equipment with fuel left in it that you need to add additives too for storage. I've done my driveway (4 cars worth of size) and two other neighbors drivers and some sidewalks on a single charge with the batteries. I do with the EGO batteries themselves were cheaper, but there's generics that are 1/3 price. If anything, if you're looking to add a tool just get with the batteries as it's much cheaper for the extra battery that way. That's what I'm considering for their 16" chainsaw.
