You cant beat a proper "Made in England" product

Make sure you know your vise sizes and designation before buying, the #23 is big enough for most jobs (starters, alternators, Jag 4-speed gearbox...) and the quick release saves a lot of frantic handle winding when you have got something heavy to secure.
There seem to be a few on the bay at the moment, I have just bought another for 50 quid.
Grab yourself a bargain, money well spent!
