already pricing given for 1000qty not bad at all.
unfortunatly the LXT related user guides ug194 EMAC ug196 GTP ug197 PCIe
are all deadlinks at the moment but hopefully those documents become available shortly.
new eval boards (besides ML501) are
ML505 - allows PCIe testing ML523 - GTP characterization board ML555 - 8x PCIe card
GTP has OOB support for PCIe/SATA and supports spread spectrum clocking as well.
