Hi dundee,
Don't believe all the nah sayers about not getting a chainsaw unless you are a total klutz around power tools.
There are some excellent battery powered tools available including chainsaws. If you have any modern battery power tools by say Makita, Milwaukie, Dewalt, or Bosch, then stick to the brand you have and look into one of their battery power chainsaws. My favourite would be Makita as I have been using them for 45 plus years with great reliable service. The new Makita 36 volt chainsaw gets pretty good reviews from experienced users. It use 2x18 volt batteries that fit as many as 160 plus, other battery driven Makita tools. Think you will have to spend a little more than $200 to get something that isn't in the lower grade consumer level. Probably closer to $300 to $350 with batteries and charger. The old adage about cry once when you buy it or cry every time you use it if you buy junk holds true when buying tools.
If you have someone experienced who can give you the basics on safety regarding use of chainsaws then that would be great, however YouTube is your friend regarding instruction. Essential Craftsman and Wranglerstar come to mind. Watch a few videos to get the hang of using one and then give it a go. Start with something on the ground and work you way to some thing up on the tree trunk. If my wife can do it I'm sure you can unless you are a total klutz with tools of any sort. If so as many have said, hire someone to do it for you.
There is however great satisfaction in doing manual work that seems to be lost on lots of people.
Makita models XUC02PT or XUC03PT would probably fit the bill well. However if you have the Dewalt or Milwaukie system them use their offering as the existing batteries/charger will work with your new chainsaw. Stay safe and use common sense, if it doesn't feel safe then it probably isn't although it will take a little time to build up confidence to do it yourself. Kind of like do it yourself investing
Thanks jb
