Hi! I'd either buy a very cheap one (< 5 Euro), because those don't support "offloading", thus reducing extra delays/jitter, OR get a specialized expensive one. I think Meinberg has a combination of hardware and software that can improve NTP accuracy. Possibly they only put it into their own servers. The following link might be interesting: http://www.meinberg.de/english/ptp-starterkit/zhw-pci.htm (I'm not speaking for Meinberg, nor do I become rich if you buy their products) NICs for NTP probably should not use a shared or low priority interrupt, also.
