You might check out these guys, if you are in Bristol, UK:
http://www.earthshineelectronics.com/
They have starter kits, along with a free ebook download to work with the kits to learn how to use the Arduino (its a really nice ebook):

Unfortunately, they are located in London, which from what I can gather is about 190 km away from Bristol (once again, if you are in the UK). They seem to be a web-store only, but you can give them a call to find out. Maybe you could order, set up a time to meet, and take a road trip? Could be a fun Saturday picnic, I suppose...?
