I last ordered a 4Gb SD card about 4 years ago just as SDHC was really taking off and I got a pair for Â£8 each. Since then I've tried ordering more and they were Â£25-Â£40! A few months ago, when updating my music collection, I lost one of those 4Gb cards, so have been looking again and just found some for Â£4.99 incl delivery!! I've ordered and received one, tested it and it's definitely NOT a SDHC, so it will work in the RNSE. Two more jsut been ordered! As much as I loath Amazon's tax-doging tactics in the UK, these guys are the only suppliers of the type of 4Gb SD cards in the UK for under Â£20!
