Unless you are giving a vise a hell of a beating every day, as in an auto garage, even a cheap cast iron vise may be OK for general hand tool use -with a few caveats below.
– The moving jaw must be a decent fit in the stock, with no excess play up down or sideways
-the screw must be decent quality steel, be an acme style thread with lands between the valleys (must not be a regular 60 degree sharp thread) and run smoothly in the nut
-the swivel base must fit decently , not allow any rock, and the screws must lock it securely.
A big list for 16.99 UK pounds, but you never know, you might find a good one.
I wouldn’t do any heavy bending or hammering on it though. Probably fine for filing or light drilling.
Note – I have found a couple of top quality ex-industrial vises for that sort of money at estate sales, flea markets etc. though, but it takes time to find a usable good one amongst all the worn out and cheap junk. Wilton and Record are two good makes.
