Yep, except 18k white gold is usually cheaper than palladium, but this depends on the specific alloy of the palladium (it is commonly alloyed with platinum-'585 platinum').Here's the order as I understand it, from lowest to highest...
sterling silver
tungsten/titanium (about the same)
14k (white or yellow)
palladium
18k (white or yellow)
platinum
However, for the elemental price points:
Palladium is currently at $507/oz.
Platinum is currently at $2088/oz.
Gold (yellow) is currently at $995/oz.

Also, good quality tungsten is significantly higher in price over titanium (~$400-500, where titanium is usually under $100).
