Any recommendations? I'd like something lightweight, reasonably stylish, and that will age respectably. So leather trim in stress parts would be a bonus, but not in the boring Hartmann way. But I'm open to interesting all-nylon designs like this one, say: http://www.flight001.com/hideo-feath...-trolley.html# I don't want to spend much -- possibly below $500, though I'm prepared to spend a bit more if I really like something. Thanks.
