If you are willing to go used, you might be able to snag an HFS-4 from an EVO or WRX part out for a decent price. I am running the CMGS, and like the controller better than the Devil's Own I had before it. I have a NIB HFS-4v3 awaiting my next vehicle.
The issues I have read about for Snow is...
There's enough to go around.
Out of curiosity, what gotchas are you looking at on the CX-7? The HPFP, turbo issues, and a few other things are worrying me. They all seem to be cheaper, and more common for sale than all other MSs combined.
Are you going to leave stock, or do some mods?
I have been looking for an MS-3, a CX-7, or a few others as a new daily driver. Currently in an LSJ power Saturn Ion Redline on E-85, and water meth. Just looking to learn more about the cars.
