I bought Satlink WS6906 last year (see link below) and use it many times for myself and friends. It's work quite good and reliable. When it locks to your satellite, you can watch the channel you like on it screen like a TV.

Somme little problems as it was designed for Europe, thus:
1.- its power connection is European type. You have to use a European to North America adaptor to charge its battery or find a 12 DCVolt/500mA adaptor.
2.- All available satellites in the unit are for Europe. You can delete them all and add your satellites and a good basic transponder for each satellite and do a blind scan when it locks to a satellite.
The unit is easy to use, I played with it for less than a hour to understand it, thus I do not need a good manual for it. The conclusion is I like it very much as I am so confortable when I use it.
You do not need to watch the unit while trying to point the disk to your satellite as this unit will sound a sonore sound to tell you it found the satellite signal. The higher signal level, the frequency between sounds is faster and when you get very high signal the sound become continuous. When the signal level is good enought, the purple light on the unit will light up telling you that it locks to the satellite. You can then scan channels and watch a channel to check the TV quality in addition to the indication of Signal and Quality of the unit to fine tune your disk.
Hope this help.
