I'd stick to either Canon or Nikon. I'd also not rule out the option of going used. You can sometimes pick up a really good deal on some used and/or slightly out of date models. Other than the nerd-gasm and bragging rights, going for a slightly higher megapixel count, etc probably isn't going to get you too much other than a bigger hole in your wallet.

Since I know the Canon line better, I'll just stick to that but... going as far back as the XTi or even the XT will probably be more than enough for what you're looking to do and you could probably find it for seriously cheap. Also, keep in mind that your skill and learning how to use your camera properly will help your photography much more than having the latest bells and whistles.

Of course avoiding the gear lust is easier said than done but, IMO and especially for entry level gear, you'll get more bang for your buck going for lenses than a higher quality body. They'll also hold their value far better for when you decide to sell your current gear and upgrade.
