The Geosat Pro 90cm dish is a good dish for starting out with Ku Band. Would recommend going fixed (single satellite) to begin with. That way you fighting with less variables and can get comfortable with aiming the dish. You can add a motor later. As for a receiver, would recommend this one - Store - Michael Electronics Satellite Dish Accessories. He is VERY active here (moderator) and will treat you right.
I haven't looked lately, but if you watch on flea bay you should be able to get the GeoSat Pro 90cm to the door for something around $100+. It will include a LNBF and mount. Do recommend putting on a pole on the GROUND, as it is much easier to work with on the ground.
Hope that helps a bit. Also be sure that you have a clear view of the southern sky. Any obstructions will kill the signal. Go to dishpointer.com and put in your Latitude and Longitude, it will help you in finding and making sure you can see the satellite.
Here in GJ I have the Geosatpro dish on a motor (I DEFINITELY recommend starting with a fixed dish first, then trying the motor). The channels you get will depend on where you aim your dish. My favorites are 87w (Louisiana PBS), 91w (news), 103W (NBC, NHK) and 125W (PBS east/west, Montana PBS, Create, World, FNX).
To figure out where to put your dish, go to dishpointer.com and type in your address. Drop the pin where you want to put the dish and see if there is anything tall that could block your line of sight.
For channels to watch, check lyngsat.com or sathint.com. You want to check the channels that show no encryption, and 5-digit transponder numbers (ku frequencies, small dish).
