While the DX-3 is considered a premium focuser, it's medium grade IMO. Its not close to the Feathertouch, Moonlight some other premium focusers IMO. As Geoff says, I would go for the GSO 10/1 Crayford which bolts straight on and is a dayyam good unit for the money. In addition to the holes all being in the right place the focal plane will also be correct. The JMI-DX3 has a much lower profile than the GSO focusers and it's unlikely to reach focus with a lot, if not all your eyepieces, without an extension tube or repositioning of the primary mirror.
