OK Trent - well you are getting a lot of good advice here. Perhaps if you want to buy new, look at Wiggle, Chain Reaction and Evans - see what takes your eye and put it up here for discussion.
As was said earlier second/hand is a great option 'cos you are likely to get a higher spec groupset and, apart from chain and cassette, the kit usually lasts a good while. So you could look on Ebay.
Only other info is how tall are you (feet/inches !!) as you want as small a frame as you can, without having too much seatpin sticking out.
You don't go near Tamworth do you as I have a mate with a shop there who is a big Villa supporter - ex National track sprinter too.
