FS: Spectral 30SS S2 high serial number

[ack]

This is my second 30SS S2, bought in July 2014, serial #30962, to replace an early S2 - there was quite a significant improvement, hence me re-buying it. This has to go now to make room for the 30SV, which is arriving within a month or two. Asking $8500, open to reasonable offers.
