Congrats to the new owner! I've seen the brace in person and the workmanship is fantastic. It is expensive for a brace, but that is the going rate for these things - check out the Yahoo Japan auctions and you'll see the older style ones like Terry's going for around $3K.
With regard to the label thing, The black label / red label remark is just a reference to the logo on the top of Terry's style of Nismo brace; his label is black; the "red label" is just the later Nismo logo which has the red "rising sun" for an "O". AFAIK the brace itself is no different.
Bobby's brace like he said is supposed to only be available for cars that were built in the Omori factory, and there was a choice between two labels, a black one that said Omori Factory and the Nismo logo. It's just a coincidence that these labels also happen to be either black or red. You can find details on them here / http://www.nismo.co.jp/omori_factory/original_menu/ttb/index.html
As EM1 said it's also aimed at people who have either got every other mod on their car, or are happy with every other mod on their car, or both. So it's a finishing piece and it's not going to be for everyone, but it does really set the engine bay off very nicely.
