There are people on flebay who don't know their backside from a hole in the ground, much less a mode hoping 532 from a direct 520, they may think WL is something special that's not available anymore as they are ignorant to the history of quality issues.
So if you find a sucker on flebay willing to pay 2k then snatch his hand off as you grab that money.....however 11 watchers and no buyers brings you here, maybe people want the BE but not at 399 ???
With a Jet you get an overspec laser with a warranty and that high quality dpss 532 beam as well as the option of a 10X Jet BE, I have a 10X Jet BE that I would sell for 85.00, I would like to find some of the separate crystal modules that WL never used, but as 1w is not much of a burner, not by my standard I would build a 1400mw 520 for 250.00 that is much more robust and less temperature sensitive.
Actually I would buy a used Jet before I bought a WL as I have seen so many glued together WL units that were way overpriced and underspec, plus lasers are wear items, they don't last forever, used is not worth the price of new unless it's a special collectible, so if you find a WL collector snatch his hand off quick before he talks to anyone who knows better.
