The drive motor
may be easier than the control head
. If you need both then you do. Are you looking for a linear drive
or hydraulic? The computer can handle a diferent drive, but it's the control head that matters. I'm in need of a course computer and the T400G can substitue for the ST7000 head (there were two control heades). The core
pack with Fluxgate
feedback all interconnect. The key to the connect is the control head. They don't make them any more.
New control heads are about $600 but the compter is almost $2000. Core
packs run about $400 more than the computer. You need to match the control head to the computer as the rest of the door prizes are easy. The economy as it is means no one stocks the big dollar items.
Most of the gear
should match a new computer but that is the expensive part aside from the installation
