Hello its my first forum post sorry!
first of all http://store.kitsch-bent.com/(quite cheap if your in the US im in the UK)
and also http://nonelectronics.com/(better if your in the UK quite fast postage really high quality stuff)
http://myworld.ebay.co.uk/gamesnguitarguy?_trksid=p2047675.l2559(great postage time but the pictures sometimes dont show the colours as pure as they really are so beware but the buttons and screens havent failed me yet!touch wood )
also you can buy chiptune on kitsch bent and non electronics but i would recommend band camp !!!
tell me what you think and help me add to the list
