Hi,
still think you're going off the deep-end. The same company I buy Delta from have their own brand ToAuto. I'm not a big fan of cheap Chinese servos, not because they don't work but the
documentation and often lack of set-up software. None-the-less the prices are very compelling....for instance this is a 2kW servo kit (servo, drive and cables) for $340USD....... that's hard to beat,
and being a matched you'll have the best probability of a good result.
