V, your right about the looks of the Achilles, it is just magnificent. The Eclipse with no engraving reminds me of the Stamer before it became Prometey.
The build quality I cant comment on since I dont have one in hand but based on the pic Uke posted - it looks like a prototype pic.
For example, the internal air posts arent finished off - meaning at the top - they are rough, need smoothed out. The other posts arent polished up - this tells me its not a production model, but a picture of a prototype. Reason I say this is - on Prometeys and Achilles ALL posts are finished off.
For build, I think its hard to beat a properly setup single coil atty. Thats only my opinion though. However, for dual coils and triple posts, I would prefer to see large holes drilled into the posts for easier set-up.
