I don't know why you guys get cold feet in the M series?  I have been in my 650 most of the day with my tenny shoes on, and not once did my feet get cold.  It hasn't fogged up yet and is nice and quiet.  Your right about the idle and the radio being on the floor, but not once have I even got close to it with my feet.  I hope that the dealer might be able to slow the idle down to around 800 or so?  Other than that it is my first nice loader I have had and I think it will work just fine!
