I have a Roksan Tabriz Zi, and a Clearaudio Satisfy arm which are both Rega geometry. I like them both better than the Rega (which I once had). They are more user friendly and adjustable (which was my primary issue with the Rega). I have them mounted on Pink Triangle tables and the Rega RB300 arm didn't get along with the the OT tables.
All that said, they are more money, and if I were putting it on a Panar 3 I'd be tempted to stick with a Rega arm.
