Got a gt2400, along with a gt2000 today. Other than needing to switch out the head, this thing is sweet. I missed my Echo, so I got 2 more. Although curved shaft, this works remarkably well. I was thinking either the curved shaft Husqvarna T25, or the curved shaft speed feed for a replacement head. Curious if they made an Echomatic/Echomatic pro for curved shafts, that would be nice.
