My Series 2 BOSS BP weighs in at 5400# and has box ways.
As close in design to a true milling center that you will
get in a knee mill.
It is easily driven by 28 in-lb servos.

It makes perfect sense to keep what you have.
I think that you feel that there are more complaints about the Gecko's
because they are probably 10 times more popular. So a lot more
people to complain. At least with Gecko you can get the owner/designer
to give you tech support.
Ask Brian Barker on the Mach forum. He has used several high end
drives including the Tek drives.
