Eddie, that's my philosophy with chain saws. I buy a Poulan , run it until it won't anymore, keep it for parts on my next Poulan. Right now I'm on my second Poulan in 10 years, not too bad.
A pole saw isn't something I use very much but I got tired, real tired, of using the manual ones. I got a refurbished electric Remington 10" pole saw from Northern Tool. I've cut limbs up to about 6" with it without a problem. When I'm out and about I run it off a 1500 watt inverter connected to the tractor battery. As I said, I don't use it too often but when I need it, it's great to have around. If I used it more often I would probably get a gas powered model but the electric one has met my needs so far.
