http://www.shotimes.com/ is a great message board for the SHO.
DO NOT get a slushbox...they're nightmares and MANY have problems. you may save some money by stepping over to the SHO but be prepared to get nickel and dimed to death. among other things, they require an extensive tuneup every 60k miles. all in all i think they're decent cars, though i like the handling and looks of the SVT MUCH better. my friend has been through a bunch of them. he started with an ATX and now has a MTX with a pretty much shot engine and trans at 90k miles. the ATX had HUGE tranny issues, even after being rebuilt it only lasted about a year. if it were my choice i'd stick it out with the SVT. just my .02
