Nice deck, I have one with an RB250 and Goldring Eroica.
Expect to pay £150 for a base deck, with a decent arm & cartridge around £250+. With the Michell unipivot arm (used to have one - damn - sold it a few yrs back)around £350...
Sound is good , also have a Thorens TD160/SME 3009 II imp/1022X, and a Michell Syncro/Technoarm/Elite..
I do enjoy vinyl...
