I have a SP10 Mk 2, PD444, and LO7D and would add simply that all three are great choices. Each will likely need to be re-capped if not already serviced. All are satisfying in stock form, but will benefit with addition of modern footers and siting, re-lube, silicon nitride bearing, etc.
Overall the Luxman is probably the most satisfying in terms of reasonable cost, superb vintage esthetic, flexibility in adapting modern or vintage tonearms, and simplicity of maintenance/DIY speed adjustment as per factory service notes with a multimeter. I found that its plinth design can be improved by substituting thick brass in place of the stock steel armboards. For a further reduction in plinth resonance, I replaced the archaic stock RCA switch box attached to the bottom of the plinth with a solid wood subplinth that serves as a pedestal for a third arm base out front that accepts standard Micro Seiki cantilevered armboards. All in all a great piece that is seldom discussed relative to other vintage DD.
