I've got the impression that discussing who and how much is a bit of a no-no around here but I think I've tried most of the modders providing these, and they're all around the $400 mark with Asian movement and superlume. Swiss is a bit more, basic lume a bit less. It seems that none of the "collectors" can supply unbranded watches.
Puretime has a superlumed 111h with Asian mvmt (which I'm perfectly OK with) for $228, although it's currently out of stock.
DSN is out for me because of the dials and cases.
