Not only will you save $150 off the regular price, but for all you CAD fans out there, this version also comes with a custom AutoDesk 123D face and build plate.

All for living the quantified life, but not really interested in tracking your sleep patterns? Garmin's Forerunner 610 may be just the thing to help monitor your workouts and save some cash. It's not the newest gadget in town, but its rain and sweat-resistant touchscreen interface can display distance, time, laps, history and more, while allowing you to leave the smartphone at home. If your workout takes you to the treadmill instead of the park, it also works with ANT+ compatible fitness machines. This deal is for a manufacturer-refurbished model, but it comes with a heart rate monitor and a one-year warranty. Plus, it earned a pretty decent 82 rating at gdgt, so it's still a solid buy.

Yep, that's right: 36.3 megapixels. Even though this shooter was released back in 2012, it's still a more than capable DSLR for professional snaps and even HD video. Image quality is one of the major benefits here, and while there may be slight delays when writing these huge RAW files to a memory card, the final results are worth the wait. Both users and critics have weighed in, resulting in a respectable gdgt Score of 88. It's still a pricey bit of kit, but this is a significant price drop, and that extra savings can be used toward a lens for this body-only offering. Don't worry, there's no shortage of Nikon lenses that are compatible with this shooter.

Hands-free interfaces like the Leap Motion controller aren't quite ready for primetime, and most people can only take so much touchpadding. So unless you're looking for Logitech's freshest offering, the Performance MX will suit your needs with aplomb. The ratings are solid and we're told this mouse will even track well on glass surfaces, reducing those annoying cursor jumps in case your office work surface was ill-planned.
