Travelling Vises

No, I'm not talking about hitting up on stewardesses or drinking too much.
My tying vise is rather heavy (its one of those with the large, brass chunk
on top. It probably weighs a kilo), so I usually leave it (and my tying
materials) behind. Now I'm wondering about getting a lighter one for when I
fly to claves. Can folks recommend a good quality travelling vise? I would
want one that is lightweight, sturdy, had good tips for small flies, and is
durable. Do they tend to be durable enough for everyday use? Is it better to
have a pedestal or a table clamp? Any other recommendations on properties of
a good travelling vice?
