Hi, I have a Vaio VGN-A397Xp laptop and have owned from new for the last 4 years. I am thinking of getting a port replicator / docking station although have been told by local Sony stores that they are no longer available for my pc. I have looked at getting one 2nd hand but have found that there are 3 different models; VGP PRA1, PRA2 and the VGP PRAV2. Can anybody please tell me the differences between the models and more importantly, if they are all or which ones are compatible with my A397XP.
Regards
Anthony
