That Sigma 105mm macro is tempting at this blowout price... though I haven't used a tele prime (w/ any regularity) in quite some time... including the MF Nikkor 105mm micro I bought used cheaply several years ago. But maybe the image stabilization will get me to use it like I used to w/ my 85mm f/1.8 (for my APS crop bodies) -- I mostly shoot my D800 in 1.2x crop (and switch to FF on occasion), which would make the 105mm similar to the 85mm in APS crop.

Ended up winning an eBay bid for a "new, other" open box (w/ 30-day return policy) for ~$435 shipped from what seems like a pretty reliable eBay dealer. Had accrued ~$130 in eBay bucks that would expire in a few days, so seems like my best option at just ~$305 out-of-pocket.
Hopefully, it arrives just in time for my trip to Rhode Island next weekend...
Thanks for the idea to consider this lens, John and Scott.
