I bought mine from these guys last year. They had a bunch of a month old Snap On SSL33 mid rise, single phase lifts for sale after doing some tyre testing for Hyundai UK. Not sure if they have any left but worth a try as the lift is superb and was much cheaper than from Snap On. Ask to speak to Jonny, he is the owner.
Another option is a full height lift but to use only up to max you can go. Daveenty has recently bought one, maybe he can comment on his experience.
And lastly, have a look at MaxJax. They are States side but can be imported if you want one badly.
