I love my Brother PT-65. Got one for work and then one for home. They go on sale regularly at Staples for $19.99 and occasionally as low as $14.99.
I prefer the fonts to the higher-end Brother labelers, it uses the inexpensive ($8.99) "M" tape, and there's much less waste (blank tape) on either side of the text. Possible downside is it only takes batteries, but by turning it off when not actively labeling, I'm still on my original set of batteries in both units!
Hope this helps,
Tom
