It really depends what brand vise you purchased, but in general, don't buy a cheap vice unless it's a expensive vise on sale.
My vise was usually $80, but I got it on sale for around $50. I don't use it alot so I'm expecting it to last many more years.
Cabelas, Bass Pro Shops, and Gander Mt. usually have some good priced vises. You could try Dick's, but they will probably be more expensive.
