Really a few others you should consider:
EAR Discmaster
Grand Prix Monaco
SME 20/2 or 20/12 (one being a little lower, one higher in price)
TW Acustic Raven AC1 or AC3 (both being under 20k)
Anyway, you have a very nice problem to have !
I own a SME 20/2, but will get a chance to hear the Grand Prix Monaco with Tri Planar arm this weekend in my system. I'll try and post a few initial comments.
