[time-nuts] Cheap 1588 cards Was: Re: Net4501

Well you sent me on a search. I know virtually zip about ptp, but this page lists a few ethernet cards that allow time stamping. Is this the same as having a 1588 card?

Can anyone recommend a cheap 1588 compatible card? I just recently saw
that the linux kernel PPS support for the cards.
