Personally I'd recomend a Cherry G83, it's really cheap, lasts ages, and feels great. Although a generic budget keyboard (about £10-£15 here in the UK) it's become really popular among PC gamers (the sort who wouldn't think twice about spending £90 on a special gaming keyboard), and personally I've used it as my primary keyboard for years, it's never let me down yet.
