I'm considering making the upgrade from Bosch 12 amp router to chinese water cooled spindle . These guys http://www.cnclinx.com/Liquid_cooled_spindles.htm have very good prices on specs perfect for my work, but I know nothing about them. Anyone ever dealt with them and especially spindles sold by them? Here's what they quoted me: "Price for the 2HP spindle with the 1/2 collette + VFD + coolant indicator is $875"
