Ive been looking and this site is so far the best ive come up with , http://www.9w2bsr.com/2008_02_01_archive.html , it also has a mpg wheel based on a optical mouse wheel like the one from the instructables site. If the mouse wheel could be replace with a mgp wheel it could be useable. On the link there is a very intresting pendant with all the functions your ever need , its a shame he didnt connect a hand wheel thou. The one thing i want is a real mpg hand wheel that at a touch of a button can go from differant jog speeds , having used these at work i know how handy they are and better than using game pad sticks to jog with. From what ive seen once you want the hand wheel the price of pendants seams too go up very quickly!.
