I have used all three and you should have no problem with either.  I've
had some WRT54GL's running in an outdoor environment for over three
years without problems.  I removed the circuit boards from the case and
installed the circuit board in the back of a Pacific Wireless panel
antenna with POE splitter.  Works great.  However, at this time, I have
found that the Ubiquiti NanoStations are hard to beat for price and
performance.  You can get a pair of these for less than the WRT54GL's,
POE's and antenna's.
