here is the PO - sorry some of the formatting might be off.
I did not just fire this off. I sent a draft first and got a proforma invoice (PI) back and then back and forth until I had the changes needed and the PI did not conflict with this (even though the level of detail on the PI is a lot less). BTW - as for the models of the drives and motors - as long as they are comparable I'll be fine. The spindle I'll be sticky on as I wanted a ceramic ceramic bearings HSD spindle as both my brother and I run 15 year old HSD's with ceramics and they still work great. I did ensure we agreed that this model was available and suitable first.
I think the biggest 'oddity' for Omni is the insistence on UL listed components and wiring labels. Let's just say we've had issues and it the wires aren't labeled UL it is a big potential problem under a worse case scenario (inspection). That added about 5% to the price.
