Underwater camera and camcorder housings tend to cost a mint and are usually hard-shell, which makes them tough to pack for travel. Ewa-marine makes dive-ready flexible bags that accommodate a wide range of digital and film cameras and camcorders and can be submerged to about 30 feet (some versions can go down to 150 feet, depending on the model of camera). Unlike pro housings, use of manual controls is limited, however some bags allow space for lights or flash units as well as long zoom lenses. Ewa-marine Housings rtsphoto.com; $100-$500

No Wires Attached
Tapeless mini-DV camcorders are much more compact than standard units, and save video to memory cards as PC-ready mpeg files. The Samsung SC-X210WL also has 1 gig of memory built-in, and is especially useful for active (or sneaky) types with a secondary wireless lens that can be clipped on helmet-cam-style to send high-quality video back to the main unit from up to 15 feet away. Samsung SC-X210WL samsung.com; $679.99

Apple Candy
The final installment in Apple’s transition to Intel-based computers, the Mac Pro is a desktop system on steroids, tricked out for power-hungry pros. Its two Dual Core Xeon processors are typically found in high-end servers–and thus make it up to two times faster than top-shelf G5 models. Apple also finally included two optical drives (16X CD/DVD burners) and left a host of slots open under the hood for DIY upgrades. Getting one still requires a few pretty pennies, however Apple insists a similarly equipped Dell is about a grand pricier. Apple Mac Pro apple.com; $2,499
