I did a lot of research and searching when I was fitting the workshop out and whilst I don't know what sort of money the MM lift is, I would suggest it's worth spending as much as you can afford.
I ended up buying a GRIP bench. The UK distributer is C&C on 01773 608909. They do a variety of benches but I guess you'd be into £500 minimum. They might deal though. Beware though, they can talk the hind legs off a donkey

The other places worthy of a mention are Probike.co.uk and Balco.
These are are all pretty much "professional" spec. and while they are worth the money, you do get what you pay for so be prepared to take a sharp breath.
