It is so thoughtful of manufacturers to provide us with a variety of options at widely ranging prices. Just remember that as the size of the item diminishes,the weight savings of titanium vs. stainless steel becomes quite small. It might not be worth the added cost of ti.

My preferred solution is a stainless steel, 16 oz. cup with folding handle (several brands) which will hold either a one liter Nalgene (if I want the capacity) or a one quart recycled sport drink bottle (lighter weight and cost). This has worked fine for solo or emergency use for me.
