Ok, so i am looking to replace my ole sears brand hedge trimmer. My question in looking at the commercials is they have the hand held type and the pole/extended type. What are the benefits of each? I know with the extended you can reach higher places with its length, but is that the only advantage? What are the advantages of the handhelds? I maintain about 20 accounts on the side and have been able to convert several of my customers to full maintenance so i think its time to invest in a nice commercial. Also, if you have a favorite one feel free to post it and why. Thanks for all the info and any help once again.
