actually the best wheel is the Thrustmaster T500 RS. they even have a facebook page Thrustmaster T500 RS - Product/Service - Founded: 2010 | Facebook !!!! lol
but for real. its the best. it is also the most expensive. somewhere along the lines of $500-600. it doesnt come with a H pattern shifter as of yet. but there is an attachment "coming soon".
but yeah. just thought i would throw this wheel in the discussion. its supposed to be the more precise wheel ever made.
