...you can get them at TigerDirect for $10 (no rebate): labeler ( $9.97), tapes ($6.99 for two-pack).
I've personally found the Brother models to waste a *ton* of tape, and the tape is of the expensive laminated variety. The Dymo, on the other hand, uses economical paper tape, doesn't waste, and runs forever on its batteries.
I bring this up because I had a client who bought a Brother and was very upset about it. I now carry some extras with me just in case they're not available locally...
Ten bucks. Good find Matt. Now I can get one for my 4-year-old daughter as well. She is learing to spell so she keeps stealing my P-touch and using all of the tape. She labels everything - including her brother and sister.
