Hmm. Is the UDM a well-tested product? It *sounds* great. I read most of the thread monitored closely by the maker of the UDM (I believe), and it seems that some of the bugs are yet to be worked out. Not that they aren't working hard and supporting those customers who have already purchased the product. From the description of the product, it sounds fantastic and an improvement over the 7424, but from what I can tell, it needs a bit of time to fully realize its potential.
Any UDM purchasers out there wanna comment on the difference between it and either the 7424 or 7336?
Here's a link to the thread I found. Very long thread that chronicles the progress of the UDM (Ultimate Detailing Machine) from idea to market.
