I've got a thumbwheel similiar to what you're asking about.
You could also just go with a street chip, race chip, and some sort of kill switch for the anti-theft.
You can get a blank thumbwheel from www.casperselectronics.com if you program your own chips. I've got the Thrasher for anti theft in my TW, along with street and race chips, and a valet chip, and then 4 slots open for me to make 4 tweaked versions and burn the chip once and see which of the 4 is best...rather than pulling chip out, putting in a tweaked version, not liking it, pulling it out, reburning, and reinstalling over and over.
