Or even Amazon (gasp). I just picked this one up for our new office and it's pretty damn nice. Lots of options and the total cost was about $80 with two kinds of tape. Whatever you get I would recommend Brother P-Touch as the tape is the most readily available. Off-brands tend to have you searching, and possibly paying, more for replacement tape.

(price jumped $10 since I ordered it last week). It might be worthwhile to add it to you Amazon cart and wait until the price drops (you'll be notified of any price changes whenever you go back to your cart, even days or weeks/months later).
