I've been of the mind that one should buy every key size available in a buy. You never know when you might find a really good deal on some keyboard, and it has very bad condition or missing keycaps. In most cases you will be covered.
I would like to revist Miami, but I am really not sure there will be the numbers required to get it made. I have some remix idea to do maybe have the flamingo and aquamarine legends on a white base. Maybe it will be more interest if it is toned down a bit?
Aquamarine on white sounds an awful lot like Raindrop... Just sayin'.
But in all seriousness, I retract what I said earlier about the Gawd-awful Miami color scheme. On a complete board it doesn't look half bad! I was thinking of the various all-white or blue keyboards I've seen posted lately, modded Filcos and CM QFRs, the Miami set would look fantastic with a case like that.
Stick to your guns, make the Miami set a reality! With ISO and 104/5-key options too, please!
