Where can I find Red 4k clips to download?

Question

Subject line pretty much sums it up. I know that they will be pretty large files, but I'd really like to play with some native Red 4k footage using CS5 and I don't have access to a Red 4k camera.
The longer the duration, the better, and each clip needs to be at least a minute long.
Also, the better quality the footage, the better as well. Seeing some good indoor and outdoor shots would be nice.
Thanks in advance!
Jim

Thanks so much everyone that replied!
Roberio's stock footage links were interesting, and RED stock footage is $$$; no, it is $$$$$
Todd, your links were interesting and useful too, even though the RED is 2k, not 4k.
Robodog2, regarding, "...testing a RED camera at home a few months ago", sweet! Thanks for your interesting link as well.
Terry, you have provided exactly what I needed to perform some simple testing, even though the files turned out to be 4.5k instead of 4k, and the longest clip is only 20 seconds. The files from this Russian site are 4480x1920, 23.976 (frame rate), and 34.4MB/sec.
I did find some actual RED 4k RAW files at the following site, but they are tiny and very boring to look at (4096x2048, 29.97 frame rate, and 37.4 MB/sec):

Also, if anyone is interested in my test results with the RED 4.5k footage on a high-end PC that does not have any special hardware installed (RED Rocket, etc.), I've summarized my findings below:
PC: Intel  i7-970 at 4.2GHz, 7x1TB RAID 5 array, and a GTX 480 with 1.5GB GDDR5 VRAM:
TEST 1a: Hardware MPE and un-rendered timeline:
- Scrubbing and playback at 1/2 resolution - perfect quality, no lag whatsoever, CPU usage around 70% (wow, that's with 6 real cores and 6 hyperthread pseudo cores!)
- Scrubbing and playback at full resolution - HORRIBLE, unusable
TEST 1b: Hardware MPE and fully rendered timeline:
- Scrubbing and playback at full resolution - perfect quality, no lag whatsoever, CPU usage around 20% for playback
- Full timeline render is pretty slow - about 9 minutes for 1 minute and 20 seconds of clips on the timeline
TEST 2a: Hardware MPE and un-rendered timeline; this time with 4 layers displayed simultaneously (each at 50% size and in a separate corner):
- Scrubbing and playback at 1/4 resolution - perfect quality, no lag whatsoever, CPU usage around 100% (again, wow!); also, I have to add that RED at only 1/4 resolution is still pretty stunning!
- Scrubbing and playback at full resolution - HORRIBLE, unusable
TEST 2b: Hardware MPE and fully rendered timeline; same 4 layers as test 2A:
- Scrubbing and playback at full resolution - perfect quality, no lag whatsoever, CPU usage around 20% for playback
- Full timeline render is again pretty slow - about 7 minutes for 4 clips around 20 seconds each
