Cryo Banks and CMV Status

Leigh
Hi everyone!!!  For those of you that used or are looking into using cryo banks - which ones did you choose?  Which were successful?  Which were problematic?  What made you choose the one you did?
Also, was CMV status important to you or no?
My wife and I are West Indian and desperately seeking a West Indian/Caribbean donor - and that has proven to be slim pickin's.  So far we've looked into Pacific Reproductive, Manhattan Cryo, California Cryo, Xytex and Fairfield.  Are we missing any good ones?  Tia Leigh
