If it's your only MF camera: keep it. I bought nearly everything (and some more) back after a few years of digital, and kicked myself for letting go at the time. At the end of the year and with no RB around, $500 will not sound very impressive anymore. I use my Rolleiflex, Rolleicord and Leica M2 only every few months, but I would miss those moments, and I did, when I had no real camera around. Think it over, and yes, if you still want to sell, break it apart.
