Can of worms about the bearing issue, clearly... in any case I'm looking to change the arm, so it shouldn't be a problem for me!
The Grace looks nice, but I wouldn't import from Australia. There's a straight Jelco? I thought all the 750s were S-shaped. I've never listened to one, but many seem to regard them highly, particularly on decks like this. They don't seem to come up on the second-hand market too frequently, though.
Perhaps I'll go for a Rega for the time being, then something more exotic. YNWaN, why would you opt for a stock RB300 over something modified?
