NEW YORK ( TheStreet) -- As much as big-iron tech vendors like Sony ( SNE), Samsung, Dell ( DELL) or HP ( HPQ) like to say their honkin' old gear makes or breaks a small business, Planet Small Biz really is still the land of the gadget.Employees are few in our shops. Everybody does everything. So little digital thing-a-ma-bobs that do not cost a fortune and do just one or two things well can actually boost the bottom line. We get lots of these units in the shop. Here are my picks for useful small-business gadgets for spring 2010: 1. Dymo LabelWriter 450 Twin Turbo label and postage printer ($200). I know, I know -- $200 for what amounts to a sticker printer is a long way to go to get some productivity. But we use the Dymo every day for labels, postage stamps, envelopes and folder designs. Dymo did a nice job upgrading its design software recently, and while the graphics tools can be clumsy, this unit offers a lot of organizational bang for the buck. If you're looking for that one magic office gadget, try the Dymo.
2. HP 900 High Capacity Inkjet Print Cartridges (starting at $14).
3. zBoost YX 510 cell phone extender ($400).
4. Spyder3Express portable monitor calibrator ($70).
5. Vue Personal Video Network (starting at $299).Security can really be a double-edged sword for the smaller shop. Having direct video supervision over your staff is nice, but actually putting in a reasonable system at a decent cost is not. I like what San Diego-based Avaak has done with its Vue, basically a plug-and-play video network that works on any Web-connected device. Just stick in a Vue video module wherever you have a broadband connection and up pops your home or office, pretty much anywhere. That's a lot of peace of mind for not a lot of dough.
