Either the revo mini, the fade crunchbox, or one of the gorilla boy bags are all excellent choices. Nutsac if you don't want to carry ANYTHING other then discs. Although I haven't seen one in person Upper Park Design's Focus seems like an awesome design, and their other bags rock.
Gorilla boy is probably the best quality bag you can get. However, with the wait time due to the individual handmade manufacturing process you'll end up having to buy another bag just to get you through the wait time. For some people this is acceptable, for some people it isn't.
And also, as previously mentioned, that discraft bag looks stupid because the discs are in it the wrong way.
