Ron Rider from Romano Martegani can make just about anthing you want in suede or calf in any last and any style. The quality is excellent and the cost is around $500 these days. You can contact him through the forum - send a pm to RIDER.
IMO double monks look funny, not as classic as single monks. Kinda in today, out tomorrow. Maybe for the under 25 crowd.
They have been around for long enough that they are classic imo and won't be "going out of style" any time soon, though not something you would wear for a conservative business environment or interview.
