I like this one, and it is unscented, affordable and available in large size bottles:http://www.amazon.com/Alba-Botanica-...8978193&sr=8-1
IMO body is too large of an area to use expensive product; I will buy good stuff for my face and hair though.
What makes more of a difference than which lotion you use, is applying the lotion DIRECTLY after toweling off after a shower, while your skin is still just slightly damp. This way it can lock in moisture that is already in the skin (moisture is actually water, not the oils - oils just help your skin to hold onto its water); and, as cacio wrote, also be careful not to use soaps that are too drying.
Hope this helps.
