For 100 meg nics, I almost exclusively use Intel Etherexpress "fxp" cards.
I've used them for a long time in servers, but now they average around $3 in
quantity on eBay and I use them in everything.  Also, many off-lease PC's
come with it on the motherboard.

For GigE, I prefer (also) Intel Etherexpress --- but the driver is "em"  (I
have not tried "igb).  I also have had no complaints with "bge" and "bce"
driver chipsets on equipped motherboards.

In both cases, I make heavy use of vlans and hardware vlan tagging.  Many
router machines have between 10 and 50 vlan interfaces.
