I have found more good deals, and posted them in another location, but thought that it was still important to post it here, as well:
8GB - 23$ Shipped
Just wanted to give an update, I also found some more links for pretty fair deals on memory cards:
This is not Class 6 like the previous one I posted, and doesn't come with Mini-SD. For me those two adaptors are really important, but maybe for others they may not be.

4GB - ~15$ Shipped
This is only 4GB, but has both adaptors and is Class 6. Under 15 shipped, so maybe this might be enough for some users, especially if you plan on getting the larger 16GB when it's price comes down.
BTW, the current price I found for 16GB is about 80 shipped:
4GB - ~15$ Shipped

16GB 80$
I am not sure, but I think that is still a little high. I think I have seen lower than that for 16GB, but this is still a Class 2. Is this as high as SDHC 16GB cards go? Or will we see higher?
16GB 80$
