Recomended NIC for router/server

[Jim Lisi]

I am puting together a server/router/firewall mashine (yes its all those 
together)
I am looking for recomendasions for a good NIC to use.  It neads to be a 
10/100baseT
(prob 100 only would be ok, since I'm useing a 10/100 switch).  I also 
nead 2 10baseT NIC
for two aDSL modems so I'm looking for somthing that won't tax my 
procesor to much
(Note: if the 10/100 NIC farly cheap (<50$CAN) I could use that for all 
of them)

TIA,
JIm
