Just to let anyone interested that the 512mb [FONT=Arial Black]Integral[/FONT] RS-MMC definitely works with the 6260. I found it hard to find out what definitely works or not so thought it might help someone looking later.
Bought mine �28.14 + �1.99 delivery from www.microdirect.co.uk for those Brits out there - cheapest I could find.
Hope this helps
