Max capacity recommended SD card for Canon A610

[gobstopper]

I've had a Canon Powershot A610 for about 18 months and it does a magnificent job for my needs.

However as I use it more and more (particularly, on occasion, for grabbing a quick movie) I find that the 512Mb SD cards which have have at my disposal get eaten up all-too quickly.

What I'm usure of is whether there is a supported maximum size, or whether I can go an get myself a nice hefty 4Gb card and expect it to work?

Thanks in advance.
