The specialty kit has too many keys, IMHO. So the price is too high for a casual "I'll add one of those to my order just in case." For example, I have one board that can benefit from the kit and it only needs a 1.75x Shift. I'm not inclined to spend $48 just to have that 1.75x Shift. At $24 I would consider it, though.
Anyhow, ordered base, colour and ISO kits. [EDIT]Oops, forgot the spacebars... added 2 to my order.[/EDIT]
Wallet has been very much hacked recently, can't buy any more keyboard related stuff for about 2 months now I reckon.
