Gas hedge trimmer recommendations

Hey guys.

I only have pole hedge trimmers since most of the bushes I do are very large privacy screens. I need to get a good all round hand gas hedge trimmer, prefer Echo, for the small bushes that are around 3 feet high. Its very cumbersome to shape a round low growing bush with a 6 foot pole hedge trimmer.

So what do you guys recommend as far as length and size that would fill the bill?

Thanks!
