I have a 5" Wilton vice that is 20 years old, been on a handful of different benches in 3 of my shops, and has held hundreds of staves, billets, boards, bows, and other jobs. It literally looks like it's maybe 2 or 3 months old.
That said, if I ever have to buy another, I'll look hard at a pattern maker's vice from Highland Woodworking. Very versatile and solid. In fact, I plan to get one if I ever get my new bench built.
