That work okay obviously! Mine broke the other week and I don't fancy shelling out £15 for a new one, more like a fiver...
Should work... just won't have the analogue in the middle. Although i think some games you do need the analogue all the time.
RE: Should be fine... There are some on eBay for a fiver plus postage, look ok? http://cgi.ebay.co.uk/QUALITY-NEW-S...hZ002QQcategoryZ11319QQtcZphotoQQcmdZViewItem
Yeah look good to me... we only have one original pad, plus one similar to that one. Looks good to me
