The Titleist drivers have been generally pretty good for a long time.
I like the 905T as a bargain driver, and you may find one with a UST V2 shaft (the yellow and black one). The maroon shaft referred to above is the Grafalloy ProLite, another great shaft.
The 907 D1 is a triangular shaped head, but the D2 is a conventional shape. It was renowned for being rather spinny, even by Titleist's rather spinny standards, but is available with some good shafts too - the Graf ProLaunch Red, I think. 909 is a good head too, available with a good made for Voodoo.
