Imho they are not going to be easy to find at a fair price (like ETA can be if you search them out) and parts will either not be available (restrictive factory policy) or hard to find for a newly introduced movement. There is one on eBay for $298.00 + $13.50 shp and that seems NOT to be much of a bargain...to me.
Sellita is another swiss made ETA clone that is reliable and a few supply houses are now stocking parts.
Q...Why am I concerned about parts availability?
A...Because parts rule the mechanical watch world. Just ask any vintage rolex watchnut. Ha!
Something else...I believe Citizen/Miyota made a mistake by not making their 9015 to ETA 28xx dial and hands spec.
Q...Why?
A...Because they are widely available, reliable, sell for $135.00 or so, and parts are available.
Here is some info on the Newton...
