my uniden is 2 watts and cost about 150 bucks
freebie from an old work, brilliant UHF
built great, communicates great, it pwns
(and you can get some really awesome headsets for it too)

Dickie Smiths should still sell them, and may have come down in price, definitely worth checking out if you think you're going to be doing any kind of long term usage with your UHF (ie, many many cruises)
