What to buy? WRT54G or WRT54GS? & port stealthing quest

I am debating the purchase of either the WRT54G or WRT54GS.

Which is better?

I see that the WRT54GS does not seem to be equipped with WPA encryption yet.

I was also wondering if LinkSys has delt with the problem of CLOSED rather than STEALTHED ports (port 113)

Which box should I buy?

Thanks,

Rich
