I was looking into buying an RSR Dyno and was told by Al Prouty (I think it was Al, the guy who repairs Fantoms) that the RSR were different in that they were older version of the dyno and a certain item which can fail (a "shunt") is no longer available for this model, so if it breaks/fails you are S.O.L.

I had an rsr.. the flywheel is different, and my dyno went capooot... They read the same, and with my rsr i had the fantom software.. I was also told no repairs..
