Any one of those bars will work. I'm not sure about the pricing; it seems like the steel Cinelli bars are cheaper than the aluminum ones, at least at Universal Cycles. Anyways, very big and strong dudes get along fine with aluminum track bars, which are stiffer and stronger than road bars. You should choose the bar based on width, reach and drop that best suits you. All those bars sweep forward enough on top so your wrists won't hit the bar when you sprint on the drops out of the saddle.

Note that the Deda bars are 31.7mm at the stem clamp, and are meant to be used with Deda stems with a 31.7mm clamp, however, you may get away with a stem with 31.8mm clamp.
