Wartree where are you?
The quality of the image is absolutely rubbish, and I can tell you that the denisty range (dMax - dMin) will be very small, and make the quality from scanning and correcting contrast really bad with scanner noise and other issues (I guess the same with printing) - and this is one of the better experimental results using that type of process!
You can buy CD-2, and CD-3 from ArtCraftChem in the US, I got 220g of CD-2 to Australia from the US for ~$40, while I know CD-4 is best for C-41 for many reasons, the quality of image you will get will be worlds and worlds apart from the link you posted, and since you're looking at the above linked process so you can simply get your hands into colour, then I think you'd be extremely happy with a CD-2 or CD-3 developer.
If you're in Australia, see my post here about getting C-41 on the cheap by mixing and matching different brands/parts -

While it may still not be up to exact standard from an all-Kodak or an all-Fuji process, I'd say you couldnt tell the difference without control strip testing etc, and it'll beat the crap you get back from many labs in this country.
You also -should- be able to get much higher quality from using the right hair dye and other mix of chemicals with proper bleach and fix than what is being done on flickr.
