@holmz - Since the RB3000 was recomemnded I would also suggest taking a look at the Audomods Arms
I've had a the old Classis Series 3 with the Micometer VTA for about 11 years and have no thoughts of changing it. The new Series 6 has many improvements
Jeff at Audiomods will answer any questions you have about his arms.
He can also make mounting plates to suite your turntable in many cases
His arms are superb, finely crafted and provide exceptional performance to any turntable
He can also recommend cartridges that match his arms perfectly
Hope that helps - Steve
