Yes, I could put up an ad after winter...
PS: Re BD, I seem to remember that somebody (Julian?) said that BDs are very expensive? Yes, I just checked and it was Julian:
But my point is that the cheapest "legitimate" price for a genuine 80 mm Sky-Watcher Black Diamond that I can confirm is around $1,000 (for just the tube, focuser, diagonal and 1 x eyepiece - no tripod or mount). This makes me think that what is being offered is not a Black Diamond, so it also makes me wonder what else is incorrect in the ad. (E.g. maybe it's not even a genuine Sky-Watcher?)
On the other hand, it might well be a genuine Sky-Watcher SW80 (but not a Black Diamond), and it may well suit you just fine.
