I know there are ton of these out there from which to choose, but I'm interested in some suggestions.

STIHL makes great products.

My tree service guys quickly saw through limbs that I would have reserved for a chain saw. They use Corona blades. You can find them at Lowe's. One more thing the tree guys did was sharpen their saws every day at lunch. Lowe's has several hand held Corona's including at least one model that folds. Their Corona pole saw is available for about 1/3 the cost of mine I put together with a swimming pool pole and special blade holder.

I tried the Corona and it worked the same for me as it did for them. I was fearless sawing through 6-inch limbs in just a few easy strokes. It was like a hot knife through butter. That was then, this is now. Fast forward a few years and my Corona saws are just like my previous saws - dull from use and rust. Today I bought a Stihl sharpening tool. I'll be using it next week. If that does not work, I'll be replacing the Corona with another one. I'm sold!
