I'm starting off with the Bikemate bicycle maintenance stand which is periodically available from Aldi or Lidl for the princely sum of £29.99.
There is a very small amount of assembly out of the box which is basically pushing the bike clamp arm into the mount on the stand itself. When folded up for storage the whole thing is quite compact, and will easily fit into a car boot.
It is also reassuringly heavy. All the clamps for tightening the stand up have very large grabbable orange wheels for turning. There is a small tray attached to the stand for holding tools and parts. It handily has a magnet fitted to the underside to keep things secure.
The bike clamp arm can rotate though 360 degrees, and extends quite a way and should grab the widest of frames. The clamp has some anti scratch soft plastic, however if you are paranoid about scratches, then a yellow duster between the clamp and the bike frame would be useful.
Here you can see my Moulton clamped by the seat post. This is setup for touring/trails and is about 14kgs in weight. Not a problem for the stand at all.
The single criticism I would have about the Bikemate stand is that the bike clamp is a screw up action. Some kind of quick release to quickly take the slack would be great, as it can be a struggle holding a heavy bike with one hand whilst tightening the clamp. Of course if you have a conventional frame with a top tube, then this would be much less of an issue.

The Bikemate stand comes with a adjustable tube with rubber straps at each end for attaching to the bars and stand to prevent the bars and front wheel from swinging around.
The bikemate stand is the equal of many more expensive stands I have used in the past from brands such as Park Tools and Minoura.
The compactness, 5 widely spaced feet and the magnetic tool tray all stand out as excellent features as does the overall quality feel. The fact that when they come on sale they are only £30 is outstanding.
The only real negative comment is that they are only available 2 or 3 times a year.
