as i don't have that kind of money, but i visited his shop in the fall of 2006 and i've seen him working...Daniel Roth's pieces are on the par with Dufour in terms of finishing...considering that he finishes a piece in about 2-3 years you can expect the highest level of watchmaking in a JDN piece...here are some pics from his shop...
and myself in front of his house where he does all the work...
cheers,
adrian
