That's my preferred card as well (SanDisk Extremes), but I have used Transcend as well in the past. The SD card is one thing I don't pay attention to price on. I just... buy... SanDisk.I've been using the SanDisk Extreme Pro for over three years, and I've had nothing but good luck with them!
Sandisk and Lexar. It's all I ever use, both in SD and CF formats.

I only shoot in 14-bit RAW and yes, the buffer does fill quickly. I think your estimate of 3 fps is pretty close and might even be a little optimistic once you hit the wall with the buffer. While this is not an issue for me, personally, I can most definitely understand how it would be aggravating to some others. It's about the only true weakness I can find in the D7100.When shooting with your D7100 in uncompressed 14bit RAW do you notice after filling your buffer that you're getting about 3 frames/sec?
...i use the Sandisk Extreme Pro 32gb. Best place imho is Evilbay (aka - eBay). There's a lot of speculation that they are fakes etc but i bought one last week and so far it's doing it's job...
