Have you checked the new Sart.org IVF success numbers?
San Diego Fertility Center has a 85% success rate with DE and a 75% success rate with DE FET. It is also more reasonably priced than our local clinics. Check the stats of your local clinic. It may be worth the 5 to 6 day trip out to San Diego (costing about $1000) to be very sure you're going to have a successful cycle.
Just my $.02.
