New Machine Build- Best BOB for use with Mach 3 ???

[jestism]

I am converting an Enco Vertical Knee mill to CNC (to supplement over flow work from my Tormach mill).

It will have (4) Axis drive controllers (Gecko G203v), stepper motors ranging from 640-1290 oz, proximity switches for limit/home referencing and a Mitsubishi FR-520 VFD for running the spindle.
Of course I want coolant control too.

What is the "Best" BOB to get to handle this combination (so that Mach3 can control the drives, spindle speed, proximity switches, coolant control, and possibly 2-3 other devices that would just need relays on the BOB.

If this is the wrong "Board" to place this question, please move it to the correct one and let me know so I can find it.

I don't want to start with a simple BOB and then find out it won't do all of those basic's above.... but then I also am not looking for a Cadillac with 100's of extras that I will never need.

I am counting on members (as I am sure a lot of you have already been there and done it) to point me to the Best BOB for my set up with a little room for expansion.

Thanks to everyone in advance.
