Brake wise, between the Prince 1500 and Gamma 6004, et all. The Prince brake is metal, where as the Gamma is plastic. $1500 is pretty good budget, many combination come to mind. If you live in area where you might be able to get a used machine, you might be able to get a decent electronic or afford a Wise 2086 Pro.
Machines: Gamma 6004 2-point w/ Wise 2086 & Babolat Sensor Dual
