Picking an extruder

[SkyMoBot]

I'm gathering up the materials to convert my CNC router to do 3d printing.   One final purchase is puzzling me, which extruder to use.   I don't want to overspend, but then I don't want to go cheap and end up fighting issues I could have avoided.   Any of you who have actually done this have a recommend ation?   I'm not at all worried about making it all work, I know I can do that.

I have a heated bed, a temperatu re controlle r, 4th Axis control.  Using slicer to generate the G-code.   My router can do 180 ipm in the XY so I'm thinking it's fast enough.
