Shooter is definitely the way to go. Last time I was quoted it was closer to the $700 figure shipped. Maybe things have changed. Got mine for $500 shipped. Keep your eye on the classifieds here. People that traded in their 06s for 08s sometimes pull them from their bikes before trading in. Even at $700, the TMax is well worth it.
If you don't plan a lot of heavy engine building mods in the future, a V&H Fuel Pak will get your air-fuel ratio right for cooler operating temps and only costs $180 new. While not as intricate and adjustable as the TMax, you can still program it for most any pipe/air cleaner/cam/ECM configuration. Installation and programming takes about 15-20 minutes.
If you like ultimate tuneability the TMax is hard to beat, but for simple mods and getting the AFR right, a Fuel Pak or PCIII is a whole lot cheaper...
