Brushed or brushless DC for my Bridgeport series 2

[jstew0903]

I am a newb so please excuse any dumb questions I ask. I have tried to search through the posts before asking these questions.

I am going to retrofit a Bridgeport series 2 cnc mill. I wanted to get your opinion on which type servo system to use. I found someone who has alot of brushless dc servos and matching drives for what seems like a good deal. About $200 per axis for servo and matching drive. I am no master at electronics but have a fair electrical background. Would it be work my time to invest the extra effort into doing a brushless setup or go with a brushed dc/ gecko 320 setup. Will a brushless dc driver and the galil pc card work with mach 3 also? I am going to be machining smaller parts and would like to get the most out of speed and accuracy. I see that if I use the brushless setup it would save me buying a 25 amp power supply (300-500 dollar savings). He says the drives priovide all the power. I plan to keep this mill for a long while so I want to get the best for the long haul. I see some posts about the low speed cogging on the brushless servos? Does this make the operation slower? I just want to get the machine done right and not look back 5 years from now and wish I would have done somthing else(that will probaly happen anyway with something I'm sure LOL) Thanks in advance for the help.

Mach3 won't control the Galil. Step and direction through the parallel port only. EMC might work, otherwise you're looking at ~$1000 for software.
