So about 5 years ago I got one of my best friends a job with my company. She is now leaving for another position in a related field. I'd like to get her a going away present/good luck at new job gift. I'm sure we'll do a communal office gift, but I wanted to get something more personal.

Her new position will still be in town, but will require her to do a lot of in-town travelling to visit different sites and occasional out-of-town travel. The only thing I've come up with so far is this super-fancy lunchbox on
Anyone have any good ideas? I'd like to spend around $50 or less.
