Hi Jim
I have the Sealey MC 365 (365kg) lift which is about the cheapest new lift available, you will need a centre stand or means block up the frame as the removable ramp is non load bearing (not to be used with a paddock stand).
With the Super Rocket strapped down well I find it easy to move into the corner when not working on it.
If I had the room I would think about a KD Bench type, longer base,robust construction and a trolley jack as the hydraulic lift, any promlems buy a new jack.
Can any one remember the Viking GB bike lift, very light weight in constuction and uses a trolley jack as the lift, can be stored vertical when not in use, some times appear on Ebay but make good money.
What every you buy its better than working on your knees.
Regards Nick
