There are a lot of 'almost, but not quite' PO's out there. If you were used to the quality of previous Omega reps, especially the Seamaster Pro's, then they will all disappoint to one degree or another (the abovementioned thread summarises the issues well).
Furthermore, as a 'hot' product, these imperfect reps are fetching a silly premium, even if they do have 'ETA' (provenance unknown) movements. Seems it is a matter of rushing a product to the market to satisfy demand.
Also, if you must have a 45mm rather than 42.5mm cased PO then you have no choice at the moment but to go for the Miyota-copy movement model. Plus side is that you can source it for less than half the cost of the ETA ones and it has probably the most accurate dial print of all of them currently. Downsides are the hour markers being too small and the caseback looks 'unfinished' (nothing a proper polishing wouldn't fix though). There are also some severe quality-control issues with certain suppliers (I will let you do your own research regarding that one!!)
My advice would be, if you've got to have one now, spend a proportion of your budget on the Asian 45mm model and enjoy wearing it for a while. In the meantime keep an eye on the forum for the bug-fixed ETA models to arrive. When they do and the initial rush-to-spend dies down you will pick one up for the change left in your budget after you bought the Asian, and you will have a weekday and weekend PO!
Believe me!!
