I will second this. I have been using Netgear 302Ts since late last year.
I have been using them on dual Xeon boards with on-board Intel Gbit NICs.
I run the on-board to a switch and use a pair of Netgears to build nearest
neighbor links. It makes for a very cost effective way to speed up CFD
runs that use 1D decompositions. The latency and bandwith of these cards
are very impressive considering their low cost and 32-bittedness.
Here is a tar file with full netpipe results for the onboard Intel thru a
switch and two Netgear 302Ts back to back:
