Purdy Neat 106NG. Pretty much bulletproof. $300. Has a computer pocket built in for your laptop. Quite tidy. I ordered from this site in the states:
www.peripatetictravel.com
Not sure if they ship across the pond. Probably work something out if you are a transatlantic flier. Free shipping in the states & free embroidered handle (where most US pilots put their name or "not yours", etc). Saves about $30 from the manufacturers site & that stopover somebody else mentioned.
Owner is a pilot with one of the US majors. Hope that helps.
Cheers
