When I buy mine for my build thats basically what I want it for.

I've also heard that it will hold the set boost better, where as a manual one may not hold the exact psi you set for, but this was a couple years ago so technology could be better or i could just be stupid.

MBC technology has "advanced" so to speak

when most people think MBC they think ok, bleed valve bleeding boost

but nowadays there are ball-and-spring MBC's that bleed very very small amounts of boost and are very accurate controllers

No, on the focus you have to change the tune with the boost level... I'm pretty sure. But like the other guy said it helps keep the boost more constant. It can also give slightly better spool up (100-200 rpm on my car) because uses the boost to hold the wastegate shut until peak boost is seen then the solenoid switches and w/g opens.

I would recommend the AEM tru-boost it is both a gauge and controller and the price aint bad either! I think they are about $300

You can tune your car for say 12psi, then run on 8 or 10 psi. It will be a smidge rich but the spark timing will be VERY close. If the tune is right (on non svt) you can take out extra timing and let the knock sensor put it back in.
Also, high octane gas (110 and such) will let you safely run 5 extra pounds of boost.
Ja-Red's recomendation is a good one. My AEM works great and I paid around 260 from CFM.

I run the Greddy Type S EBC and I love it... I also have a remote switch so I can go from low boost to high boost as I please.

Agreed Pete. TurboSmart has some really nice MBC's that have very minimal leak issues for less than $100 bucks.

The bad thing about MBCs is that you can over dial your boost settings if your not paying attention (i.e. dialing on the fly or not staying within your tune parameters.) With an EBC set up something like John's remote switch for hi/low boost is best. You can set it and forget it.
