Brother PT-18R
I bought the Brother PT-18R on DA's recommendation and love it. The neat thing about it is that the amount of wasted label is negligible, so your investment in tape is maximized. I also love the insta-print from PC function via the attached USB cable. I set up hotkeys to start the little P-touch app, a few keystrokes, and voila! The label pops out next to my computer.
