Ok gofer....... for another TOP link (imho) - this time it's for RAM for just about every gadget that could do with some.... and specifiying what you need couldn't be easier ( you'll see why when you try the site )
So, have a look at:
Crucial Technology - The Memory Experts ( the UK page )
Nb. For other countries use their drop down list - which you'll find in the top left of the UK page, or alternatively look at their home page at:

I purchased ( on-line, from their UK page ) a 256Mb Flash for my Canon G2 ( to replace the 32Mb that it came with - but which I now keep a as spare, just in case I manage to fill the new one - which I'll admit is unlikely ! ).
I placed the order at about 11am on a Monday and it arrived in the post the following morning !
I've similarly also ordered RAM for laptops and desktop computers and have been equally impressed with the delivery and prices !
Ps. (hence the edit) - gofer, I've just checked on Crucial and for your Canon Digital Ixus they'd currently charge you just short of
£65 for a
256Mb compact FlashCard.
and where to put that into context..... e.g. at
'PC World' they will charge you £70 for only 128Mb, i.e. you'd be paying £5 more money to get only half as much RAM.
So please trust me when I say that Crucial are a
very impressive supplier of all things memory !!!
