Dynavector DRT XV-1s

Looking for some help.  Thinking about auditioning said cartridge.  Does anyone know the going US rate for a rebuilt Dynavector DRT XV-1s?  Thanks!!
The rebuild cost is very high. To my recollection, either 70 or 80% of retail price of a new cart.
Had mine done about a year ago, $2600 through Needle Doctor. I bought mine used and now it's basically gutted and rebuilt by Dynavector as new. If you trust the source, it's unplayed and certified rebuilt by Dynavector, I'd say 75% of retail is a great deal.
Thanks!  Much appreciated!!!
