I actually just bought this on Amazon. Not advertised on the Slooh site, but seems like a pretty good deal to me to get started. http://www.amazon.com/Slooh-Telescope-Minute-Mission-Card/dp/B000YZCHJ8/ref=sr_1_1?ie=UTF8&qid=1358105739&sr=8-1&keywords=slooh

Can't wait to try it!

Would really like to hear more of other impressions of Slooh. Have not used it yet, but kept reading and reading about it.
