I hope the OP didn't waste any money on Rega upgrades since the Rotel was a rebadged Systemdek. The Rega sub-platter upgrades will not fit the Rotel, repeat WILL NOT, although any Rega tonearm will drop right in. The 900 is a very nice turntable. I have the model discussed here and would love to have one of the earlier 900s, which are gorgeous.
