I am in the process of purchasing a Meade RCX400 12" with the DSI Pro CCD. I have read in several places that Autostar's drizzle feature can correct the rotation problem introduced when taking long exposures with an AltAz mounting. Should I rely on drizzle to correct this problem or should I invest in a wedge so that the scope will operate in RADec and eliminate the problem?

Your experiences/opinions would be greatly appreciated.

IMO to eliminate all of the rotation I would get a wedge.
Even in drizzel you will still get rotation in the image especially at that high focal length.
Id strongly recommend a wedge.
