I always love the label makers from DYMO, and I can attest to the power of the LabelManager 500 Touch Screen label maker.
I had a chance to try out the LetraTag Plus LT-100H personal label maker, which is a real handheld unit. It is made for the home or the office, and this one is completely battery-powered with 4 AA batteries.
The LT-100H has many font styles, with underlining, bold style, and all kinds of text sizes. The screen shows what the text will look like before you print it, which is quite interesting. I found that there was interesting forms of crocodiles, flowers, hearts, and all that stuff.
You should be able to get the LetraTag Plus LT-100H on the Dymo site for about $29.95. Not a bad price, and good for labeling anything, yeah!
