I have had a few enquiries about the best place to buy a Raspberry Pi, which we are investigating as low cost PCs. Here is one dressed in Strawberries and Cream, browsing Hwb.
The best place to get them from is the official supplier, right here is Wales, RS Components. You will get the official units, also made right here in Wales!
For those interested, here are the links to build a working system, correct at the time of writing:

You will probably also need an HDMI to VGA adapter – I have tested these ok:
You might also want to get a camera, but there are lots of ideas online for projects.
