I've looked forward to the reports to be made between the ART 20 vs ART 1000x.
The initial descriptions are good and the differences detected are with similarities to a comparison of same Brand Cart's I was once party to. There is opportunity to have much extended experiences with the ART's in conjunction with the 1000x taking on more usage hours, the info supplied will become more valuable to others with an interest in such models.
It is also good to see how recollections of other Brand Cart's having been experienced in use, with a not too different price tag are a comparison.
With there being approx' ($2K - £2K - Euro 2K) additional price for the 1000x, I am sure there is a lot of Thread visits to come, where there is a thread like this one.
