EXOvault artists hand-build fine iPhone cases (3G/3GS or iPhone 4) of metal and wood. Each case is machined from solid metal stock, and some have rosewood accents. Some cases are plain, and some are engraved. You can choose a style that screws together, or a style with hinges for easier removal of the iPhone. The price varies with the particular style and phone combination; prices are from about $70 to about $205. They even have four cases for iPod touch that are priced from $70 to $90. Visit the EXOvault website to see all the styles and designs available.
