Filled out the form.
I am especially interested in the thick PBT sets.
I prefer the grey tones, because blank sets in black / white are readily available.
Also, I'd prefer 1tone sets. At these prices I'd prefer to buy two sets for mix 'n' match. This way people can choose between classic and symmectrical look ("`~" and "\|" keys).
Concerning ISO it would be great if each set contained an extra 1.25 key (as left shift) and 2 extra alphas.
People could use the enter keys from other sets. An Enter key in a different color would be a nice accent on a blank set I think
