SD Card Help Please

I am almost 100% decided that I will purchase a PowerShot A710is as my next digital camera, my next decision is what to purchase as the memory card (SD format).

I believe that 2GB capacity will suit me just fine. If I am on an extended trip without a chance to download my pics to a computer I can always carry an extra card or two, so 4GB isn't necessary.

The only issue that I am not quite sure about is card speed. Shopping online at Staples.ca I have found one 2GB card (with reader, although I don't need the reader) for $54.98 CDN, and another 2GB card for $129.76 CDN, and another 2GB card for $109.84 CDN. I assume the biggest difference is transfer speed. The only one that clearly says what speed it is is the most expensive one (60x).

Does my camera require a certain speed to take quality video, or rapidly successive high-res pics, or will even the most basic SD card suffice for the PS A710is?

Also, does make or model of SD card matter much?

Thanks so much for any help, and I hope the links to each card work...

You don't need the fastest card that's available out there because the Powershot won't be able to make use of that speed. However, don't buy the cheapest and the slowest card, either, because the Powershot will be able to transfer files to the card faster than these cards can write them. What you should look for is something in the middle which is fast, yet affordable. If you get one that's slightly faster than what the Powershot can do, that's OK, too, since the next camera you get might be able to take advantage of the speed.

As for the brand, some people will use whatever they can get their hands on as long as it's cheap while some others only get brand name products. In this case, get whatever you feel comfortable with. I personally have only used Lexar and SanDisk cards (SanDisk only for the SD cards) and have never had problems with them. The SanDisk Ultra II SD cards are pretty fast yet affordable.
