Sasha, there's lots of info/web site addresses and personal experiences of other clinics in Spain and elsewhere in europe on the
www.ivfconnections.com threads. Suggest you look at those on WW (wondeful women) thread, and others which talk about the IVI chain of clinics in barcleona, Valencia and Madrid etc (cheaper than IM I understand). Also there's info on one thread about the Czech Republic (quite a bit cheaper than Spain and lots of blue eyed donors, apparently).
I'm off to Ceram myself, so will let you know how I get on!
Good luck,
Kitti
