I was just looking at assorted clinics in SC last week and yesterday I spoke to one of the new pt coordinators. Southeastern Fertility Centerhttp://www.sefertility.com/research.html is conducting a frozen donor egg study, and the cycle costs the IP $5k, not including IP's meds and dx testing. Age limit for IP is given as 50 on the website, although the coordinator told me 49. The donors are anon and under age 32. The clinic has excellent success rates.
Disclaimer: I am not their pt, although I've asked them to consider me. (I'm on the age cusp, and there are some other conditions I've asked them to meet.) And 10 years ago, I was very unhappy with their protocol for treating women in their 40s, so I didn't go to them for OE ivf.
So far, SFC has completed only 2 cycles within the clinical trial using the frozen donor eggs (vitrified, really), with 1 pg and 1 bfn, although apparently more are on-going.
