A refurbished Sota Sapphire is definitely the way to go. I have one with a modified Sumiko FT-3 tonearm. Bought it from a friend who is one of the more distinguished members of the A'gon community!
This is the best tt I ever owned. Easily surpasses the SQ of a Well-Tempered tt I had. $4000 should get you a refurb Sapphire and decent tonearm. IMHO :-)
