MachMotion vs. DIY for a Bridgeport

I have a Bridgeport Interact CNC mill. It was one of those great eBay
deals. Bought the machine from a vo-tech school for $300, but they
had been using this particular one for spare parts. Needless to say I
have none of the CNC controls.

After searching the Internet far and why I see where some people
would use stepper motor systems, but apparently they do have some
shortfalls in performance, on the flip side they're affordable if you
can decide what components are compatible we teach other. Another
solution is to collect the necessary components for a servo control
system. The performance is better, a bit more expensive and more
difficult to tune.

This is my dilemma I'm not an electronic guy. I've been trying to
learn enough to understand the nomenclature from each breakout board
manufacturer, but this seems to be overwhelming for me. What I'm
scared of is buying a couple thousand dollars worth of parts and then
once I start sitting down to wire everything things are not
compatible and "magic smoke" starts pouring out of things. This is
the chance when you DIY. I do everything myself except electronics.
Making the brackets for motors etc. is no problem but selecting
electronic components that are compatible is a problem.

My dilemma is do, I buy a complete system from MachMotion, or do I
attempt to DIY. The Mach Motion system will run around $6,000, but it
seems to be pretty close to state-of-the-art for a guy that has a one-
man machine shop. I figure I could do is stepper system myself for
about $2500, or attempt to servo system for about $3500. The $6,000
price tag is a little bit out of my budget but not enough to where I
couldn't scrape up a little extra money here and there.

I'm sure some of you have built stepper systems for a Bridgeport that
work very well, and others have built servo systems that do just as
good. When you consider the amount of time that you spent assembling
the system versus simply purchasing a complete turnkey system, what
does hindsight tell you?

So what's your opinion?
