For example, I'm seriously considering the WRT310N. The specs says that is has a "Built-in 4-port, full-duplex 10/100/1000 Gigabit Ethernet switch to connect wired-network PCs and devices."
if you are already spending $99.99 + tax in store I would consider going on line and looking at newegg.com
Even thought it is only draftN not draftN 2 i like the WRT610N personally but I am broke at the moment so I an forced to play the waiting game.
Another bonus is that the WRT610N should soon be a fully supported DD-WRT router. As of now it is still being tested. So I would run the most updated linksys firmware till the bugs are worked out.
and if you don't really care about 3rd praty firmware these are my picks.
