HELP! Echo hedge trimmers

[STOVE]

What older models of echo hedge trimmers are worth a hoot, and are there any duds to stay away from?

I have an edger and string trimmer already so I am not looking to get the 2620 interchangeable. Should have gone that route from the get go but it is what it is.

They are all pretty good. The new HC 2020 has a simpler and slightly more reliable gearbox design. I saw a few clutch drum/shaft separations on the HC 152, but that was only on extremely high hour machines (think thousands of hours).
