VXPocket (V2) by Digigram

The big advantage of this card is that it can be used in most laptops since it is a PCMCIA card. This card is a good solution if you need to do high quality measurements with your laptop without using a docking station. Several professional users are using it with WinMLS. The user support on the card is good.
