So the best out of the box DSSD with ETA comes from a factory we call the N-Factory. They are around $200 apiece.
There is a modder on this board who takes the stock DSSD from the N-Factory and applies his QC checks and custom datewheel to the watch, and re-sells them as "new with modifications" .. that member is BKLM1234 also known as "BK" ..for his current pricing, you should contact him directly but it will be north of 400 US.
To find the NoobFactory DSSD, just go to any of the trusted dealers on this forum .. like Trusty Time, KingWatch, Perfect Clones, ETC ...
Be aware that it is the very beginning of Chinese New Year and that can delay orders/shipments from China for up to 3-4 weeks.
