[update]
As some PMs concern, I contacted ZWO again and clear some points:
1. ASI120 cameras have two types, mono (120MM) and colour (120MC). Mono one is more sensitive than colour one. Because we buy as a group-purchase, ZWO would like to offer a further discount to incent more potential users. That is 270$ for 120MM and 250$ for 120MC (You have to pay for postage in Aus or local pick from Wollongong). So who have ordered please PM me which one you want, mono or colour one.
Anyone could also buy from their website directly, they will charge shipping from next year (20 days left for free shipping) http://www.zwoptical.com/Eng/index.asp
2. The whole set includes camera, USB cable, wide angle (150 degree) lens, M42-1.25" T adapter and IR-CUT filter. Driver and imaging software via download from their website. And they offer two years warranty.
Besides the functions of imaging and guiding, the wide angle lens could be used to monitor the weather for a remote observatory or capture meteors, etc

3. I have never used ASI120 cameras, only kept an eye for months and read some posts on internet, so no user experience from me. But pics could be found through websites.
