I have something extremely like the Sealey X lift but without the Sealey name on it, which probably reduces the price somewhat. In its original form it is ok for a centre stand bike but considerably too short for a rear stand bike. So mine has been modified somewhat so that I can just get a rear stand bike onto it by means of an extension to the front. This is not something I would advise others to follow blindly as the action of the X system when raising the table leads to a danger of overturning forwards if you were sufficiently incautious. So as a relatively light and easily moved ramp for centre stand bikes it is fine - but not at all easy to use for a rear stand bike.
