I would NOT buy a cheap "look alike vise" on ebay or anywhere else, I've done this and its JUNK!!!! Ive spent more money trying to save money than i can count. Sometimes you should just buck up and buy what you want cause it will cost you less in the future.
Just one that Ive been looking at buying as soon as uncle sam GIVES ME MY MONEY!!!! is the Anvil Vise. I have heard good things about it, but its not sold in fly shops, i think their site it
Anvilusa.com. Great looking vise and all around 150 bucks.

I would look for rotary, you may not use it now or that much but good to have on it.
