I live in the UK and am looking to buy a mechanical keyboard within £40-£50, or about $65 US. I'm not really bothered what features it has, however RGB backlighting of some kind would be nice (not vital though). If I can't get a mechanical keyboard for that price then please give advice on a good alternative.
Any suggestions on where to buy metal keys and how much they would cost would also be appreciated.
Edit:
Thanks for all the replies, I don't know too much about keyboards, so the help is much appreciated.
