Hi SA,
to the forum!
How did you hear about us?
There's a tonne of info about the GSO dobs on this forum, there's been many a purchase of these in the last 6-12 months (through recommendations here) and there hasn't been an unhappy customer yet. For the cost, they're unbeatable value for money.. big aperture for under $1k.
The ToUcam is a webcam, it can be used for plantery and lunar imaging. It connects to a laptop/PC and records video through the telescope (you use it in place of an eyepiece). The telescope acts like a large telephoto lens. Processing of the resulting video then let's you extract the best frames in moments of good seeing to produce the final image.
If you're interested in imaging, you should read the article I wrote,
Astrophotography with a dob. Whether you plan to do imaging with a dob or not (it is difficult and time consuming!), it contains some useful info to get you started.
If you're on a budget of $1k, the dob is definitely the best option for large aperture. If you want something smaller and portable with goto, then the ETX is the best option.
Oh btw, where abouts do you live?
