I found it interesting that the Gold and Red were $99 and the Blue and Green were $119. I like the Red anyway, but why does Blue and Green cost $20 more to produce?

Also, where's the scroll lock key on the 82-Key?? Very important to KVM users like myself?

The blue (Ice) model and green (Toxic) model cost more because the LEDs cost more to manufacture.

There is no scroll lock key on the 82-key Deck, however we will be taking this into consideration if we ever make a revision to this product.
