REI's raingear made with eVent fabric is awesome.  I think my jacket is a Kimtah.  I have had it for 3 or 4 years, and it is truly waterproof and truly breathable, much more than Goretex.  I just bought the eVent waterproof pants on sale.  I wore them skiing last week and am amazed how comfortable and breathable they are.  They are not cheap, but are worth the money if you spend much time in the rain.  I layer base and fleece under them and wear them year-round.
