When I last talked to Glenn, it seems we needed far more yellow orders; I don't know if we're there with 447 yet... I think 589 is the spot where this group buy needs some love...
Here's something that might motivate people... If this GB#11 is so hard to "trigger", and get the right quantities -- its possible that this could be the last GB in a long time.
So if you've been sitting on the fence on a 589, this may be the time. I really think that this whole Arctic thing set the entire hobbyist laser 'scene' on its head.
The "extreme burning guys" have been satisfied at a really low price (though 445/447 is a really nice WL) but some of us "wavelength guys" seem to be not getting any benefit.. (which I suppose makes sense, since DPSS demand in any sort just went down.)
Anyways, I do wish Glenn would let us know how many of each we still need, I think that'd motivate folks too.
