Router recommendations?

  It appears the radio in my WRT54G (ver 2) has gone insane.  It
appears in SSID lists but connects are never successful.  I've tried
loading OEM firmware and it didn't help.  So, I thought I'd ask: What
would people here recommend as a replacement?

  I'd like to run "open" Linux firmware on whatever I get.  I know I
could just get a WRT54GL, but I'm wondering if other brands/models are
"better".  I'm not currently looking to have it do anything more than
be an Internet gateway and WAP, but if I can pay the same and get
more, or pay less and get the same, I'm all for that.  :)  I suppose a
USB port for various kinds of future expansion would be nice.

  I'm also wondering about 802.11n.  It seems like now would be the
time to invest in new technology, and lots of "Draft-N" stuff is out
there.  On the other hand, 802.11n seems to be in perpetual
development.  I know they've made major changes to it once
(invalidating a bunch of old "Pre-N" stuff).  And I know there's a
patent issue with the current stuff.  I'd hate to pay more for
something that ends up being a dead-end.  I also don't have any other
802.11n hardware, so the extra capability would go unused at first.

  Opinions and thoughts welcomed.  :)
