VGA is old technology how old are the monitors? or are they cheap ones?
if they want a big screen get a 30in the macbook pro's shoud drive it o.k. they make a dual link dvi adaptor especially for it.
If its one of the newer macbook pro's or the older 1 inch with half a gig of graphics card memory then it will drive the 30 inch fine, but if its the older/newer 15 inch with 256mb it will not drive it at full resolution as it hasn't got enough grunt so you might as well go for the next size monitor down and suffer no drop in performance.
