Mystyler,
I paid $85 for a little 12 inch saw a couple of years ago, it has been a fantastic little machine, I use it one handed all the time cutting up pallets for firewood. I bought it wanting it to do one job cutting the top off a palm tree that I was not prepared to cut using my big Stihl above my head. Since then I have used it so much and for that price if it gave up now I could not complain and I would race out and buy another one. I think it is called a TDKMAN. I don't think your pole saw would be a 3/8th chain
