I found these a while ago but have only just got around to trying them....

The range is ideal (50cm), it not very expensive (£2) and doesn't need may external parts. The trouble I've got is the size of the component, it's just too small for home made boards - it's pushing the limits of the machine I can access.

For scale the holes are 1mm with a 0.1" pitch for the 3 pin header in the middle of the board.

The issues for me are the scale of tracks and the consistency of soldering with a lack of solder resist.
