I use a Brother PT-H100 printer, which is about $20. The printing doesn't fade, it's perfectly legible, and for making more than 2 or 3 labels it's faster than writing by hand.

I've never seen any at TJ stores here in San Francisco. For one thing, they're not very forgiving of unfavorable environments, and if they aren't kept moist they'll croak pretty quickly.
