As with most 602 owners, my proprietary excello power feed isn't working (honestly, like most it isn't even all there). Since this is my home mill, I was going to just throw on a cheap Chinese servo bridgeport style power feed. I'm curious which of the few available models would be the easiest for me to retrofit, or is best as far as value, and if anyone has any idea what I'm getting into would be nice to know. Thanks!
