SanDisk's 512MB SD card is by far the cheapest available. In most cases, the other cards are at least 50% more than this one.
I was curious about speed since SanDisk is known for being a bit on the slow side. This card was relatively newly released when I wanted it, so I was unable to find any good speed figures online. Therefore, I bought it anyway -- and ran the speed tests myself.
Testing on a Toshiba/AudioVox Genio e550G with Kai's Speed Test application, I ran the Write Test 5 times with the following results:
Trial #1: 263KB/Sec
Trial #2: 263KB/Sec
Trial #3: 181KB/Sec
Trial #4: 171KB/Sec
Trial #5: 196KB/Sec
Not very consistent, for some reason. I was not running any other applications at the time, so I am not sure why the fluctuation.
For comparison, here are the results using a Lexar 256MB SD card:
Trial #1: 263KB/Sec
Trial #2: 271KB/Sec
Trial #3: 279KB/Sec
Trial #4: 256KB/Sec
Trial #5: 256KB/Sec
So, at their best, the two cards seem quite comparable. It is just that the Lexar card is clearly more stable as far as speed fluctuations go.
In any case, I'm happy with it -- especially for the huge difference in price in most cases. Works for me. Plus, 5-year warranty -- just in case.

---UPDATE---
The fact that the card always performed well for the first two tests but then slowed and stayed slow until the device was reset was really bothering me, so I contacted SanDisk about it and gave them the same results that I shared here. SanDisk said that they thought the card was defective! I therefore had this card replaced (very quickly and easily by Amazon, I will add) and have just repeated my tests with the new card. Good news! The replacement card is usually faster and much more consistent than the original! It no longer slows down after the first two tests -- the results are repeatable at any time.
For comparison, here are the new figures for the 512MB SanDisk card:
Trial #1: 329KB/Sec
Trial #2: 263KB/Sec
Trial #3: 341KB/Sec
Trial #4: 279KB/Sec
Trial #5: 318KB/Sec
As you can see, the card is now performing at or above the speed of the 256MB Lexar that I had previously tested. I am now quite satisfied with this card -- it appears to be giving the same speeds or better than other cards well above this price range.
