We have not got around to a FYI/Newbie guide yet, good idea.
Most people start out with a 30" dish, I recommend the Winegard dish rather than the slightly cheaper Hotdish, it just makes life easier : ) You will need a standard Ku band LNBF or a universal ku band LNBF for a wider frequency range, if you get a universal its a good idea to get a standard at the same time as you (or installer with meter) may need one to point the dish, As for the motor the most popular model must be the SG2100 it can be added at any time to a system as long as the receiver is DiSEqC 1.2 compatible, a blind/smart search is really a must these days especially if you want to keep up with all the news feeds as they come and go.
I would say the two most popular receivers right now that really "do it all" are the Pansat2500 and the Satwork 3688, the Pansat has the USALS function but other than that its a personal preference and value for money issue, the software on both of them can be upgraded if needed.
The news feeds make it worth it alone make sure you get set up before the big convention next week, the feeds will be jumping, hope this helps a bit I am sure the other guys will chip in too......
