I need to purchase a gas powered hedge trimmer for some upcoming jobs. My options are all around $260. They are the Echo 150, Shindaiwa 22 or RedMax 2200. All trimmers are right around 22cc. Echo has a 20" bar, Shindaiwa and RedMax has 22" bar. Shindaiwa's the lightest, then RedMax, then Echo. Any suggestions on which one I should get?
