By Lou Carlozo, dealnews contributor Technology is great when it works right. But otherwise it can be aggravating when your email server breaks down and your printer jams up. How's a serious working person, entrepreneur, gamer, or blogger supposed to keep up with all the cool new gadgets and gizmos out there when the basics don't stand up? To save you from a total meltdown, you might need to upgrade a few things. We've rounded up five bargains that include a backlit keyboard, surround speaker system, and a coupon to help with your cable and power supply needs. We did the homework, we scoured for the bargains, now all you have to do is point, click, and purchase. Belkin Coupon Discount: 50% off select items via coupon code "BIGGAME" Shipping: Starting at $7.50 s&h Expires: February 29 Is It Worth It?: With this deal, Belkin cuts 50% off select power products and cables, with no minimum purchase required. That's a fabulous discount given Belkin's reputation for making quality cables and power strips, and the best discount we've seen from them since December, when they took 50% off sitewide. We like the Belkin 6-Outlet Surge Protector (pictured) for $9.99 before coupon, $5 after. With $7.50 for shipping, that's the lowest total price we could find by a buck, although most merchants charge closer to $20. This surge protector features a 4-foot cord, 630-joule energy rating, and more. Toshiba 14" Mobile USB LCD Display Vendor: TigerDirect Price: $179.99 with free shipping Lowest By: $50 Is It Worth It?: This foldable 1"-thick display is the perfect way to add screen space to any Windows device, and it can offer convenience for, say, a small presentation on the go. Connecting via USB, this display features a 720p native resolution, 16ms response time, up to 220 cd/m² brightness (via optional AC adapter, not included), 400:1 contrast ratio, and more. It weighs less than 3 lbs., so it's easy to carry, too. Gateway 23" 1080p LED-Backlit LCD Display Vendor: Best Buy Price: $139.99 with free shipping Lowest By: $70 Is It Worth It?: As monitors go, 23" is large, but not usually cheap. At $139.99 with free shipping, we're talking a price normally befitting a much smaller screen. This Editors' Choice monitor features a 1080p native resolution, 5ms response time, 250 cd/m² brightness, one HDMI input, and DVI and VGA inputs, and more. The average of BestBuy reviews is about 4 stars praising it for crisp picture resolution. Iogear Wireless LED-Backlit Mini Keyboard Vendor: newegg Price: $39.99 via $5 mail-in rebate with free shipping Lowest By: $15 Expires: February 16 Is It Worth It?: The 13 customer reviews on newegg give this keyboard a composite 4 out of 5 stars. (Actually newegg uses eggs, but you know.) This LED-backlit keyboard features an optical trackball with 400, 800, and 1200 dpi resolutions, scroll wheel, and more. It also boasts a built-in optical trackball which allows you to work up to 33 feet away from your computer/laptop, home theater system, or video game console. Refurbished Logitech Z506 5.1 Surround Speaker System Vendor: Meritline Discount: $49.99 via coupon code "MLCK021BNL1" with free shipping Lowest by: $10 Is It Worth It?: At this price, you'd be lucky to secure just the down-firing subwoofer. But you get more than that from Meritline. This Logitech ensemble runs on 75 watts RMS of total power, and features 45Hz to 20kHz frequency response, 3.5mm audio input, and more. While 75 watts isn't a ton of power, it should do the job as an apartment or small living room sound system. This audio system is compatible with computers, music players, TVs, DVD players, and other audio sources with 3.5 mm or RCA audio out (not included); it also works with PlayStation 2 and 3, Xbox 360, and Wii. Note that no warranty information is supplied. Front page photo credit: Cheezburger Lou Carlozo is a dealnews contributing writer.
