First step is to decide what storage medium you want; mini-DV, DVD, hdd or flash....
mini-dv is the old type, offers good quality but is cumbersome to use. HDD/Flash are more pular these days and also a bit more expensive
JVC/SONY/Panasonic/Canon are the main brands,
you also have 2 types, Standard def and high-def,
some new popular models within your price range are the canon hf100, and sony sr12/11
Also for high-def camcorders, sony has a slightly better reputation than canon....
