I have a Hitachi VFD connected to the Avid Control Box that controls an 80mm 2.2kW water cooled spindle. Works great! If I were building another machine, I would likely go with Avid's spindle and controls. However the VFD, cabinet and spindle cost less than $1K. If you go the none Avid route, save yourself a lot of problems and buy the cable that connects the control box to the vfd from Avid unless your an expert in soldering small electrical connections. Its not that expensive and you can cut it in half and have a spare cable.
