The red one is $80 and I think it looks awesome.
Anyway. I have the black one and I paid a lot more than $75 for it about, uhm, maybe 2 years back. Definately a good set.
Have you tried searching ebay for old ibm model m keyboards? I have one from the early 90's and it works great for me. I think i got mine for around $40 a year or two back.
The keyboards you are referring to are known as mechanical keyboards.
After not getting into the early access today for SWTOR I thought "hmmm, it's not so bad, Back to Karkand releases today for BF3, i'll play that!". Nope. Origin has been down all day for me and many others.
