The melee characters tend to be very item-intensive near the latter end of the game, and thus most people start out with something like the Skellimancer or Meteorb sorc, which do not need that much good gear, and then use them to magic find for the other characters. But if your heart is set on a meleer, a frost zealot would be a good choice. All you need is crushing blow, a few pieces of plus skills equipment, and you're set. There is a guide in the paladin forum. Also, if you can build of a small store of perfect gems, you can buy the Immortal King Set, which apparently makes for a hell-viable whirlwind barbarian. I've never made one, but I have read that it works well. There are also melee assassin builds, just browse through the character forums and look at guides. Whatever you build, if it's a meleer you'll want maxed block with your shield, as close to maxed resists in hell as you can get, a whole lot of life, and some damage reduction if you can get it.
