This is a Logitech QuickCam 4000 webcam, barely used and not modified.
I opened the case and found some good news, hence the higher-than-usual price. QC4000's are found with any of 3 different imaging CCD's: the Sony ICX098BQ, Sony ICX098AK, or the Sharp LZ24BP. The Sony BQ is the best, with higher sensitivity and lower noise than the other two. (It's the same CCD as the Toucam Pro 740, which most agree is the best budget webcam out there for astrophotography.) Anyway, by luck of the draw this QC4000 has the Sony BQ version CCD. It can be modified for long exposure.
Price includes shipping CONUS. Thanks for looking,
