Which cart. with Clearaudio Unify & Teres 255?

After 15 years in the digital darkness I'm jumping back into vinyl and have ordered a Teres 255 turntable with a Clearaudio Unify arm. Now I'm clueless as to what cartridge to use with this rig. I've heard great things about the Shelter 901, but have also seen warnings here that the compliance of this cart. might be too low for the Unify, which is a unipivot design and which the Teres website says "wobbles a lot." Chris Brady of Teres mentioned the Benz Ruby 2 as a possibility. Any other ideas in the under 2K range?

If it matters, this will be used with a Supratek Cortese preamp and Dunlavy SC-IV speakers. I'm also shopping for an amp, but that's another thread.
