Hi Guys, I am thinking of upgrading my manual Eagnas to put in the Wise 2086 tension head on top of it. (http://www.youtube.com/watch?v=PQxGSO4Cegg) Is it worth it to upgrade the Wise 2086 tension head or should I buy another electrical machine and sell this manual one? Any table top Electrical stringing machines do you all recommend ? Price wise around $1k USD. any Advice please?
