I had an in-motion Trac King installed by the factory about 2 years ago (BTW, excellent installation job with a matching wall inside a cabinet, for the sat display).
It has performed well and seems always to get Sat signals.
However, I use Dishnet, which required a manual selection of different sats, followed by a tedious 2+ minute sat receiver reset.
I understand this issue caused DirectTV and perhaps other sat makes to be favored choices.
I recently contacted them (BTW, great customer service) to inquire about loading coordinates for the 129 sat (had 110/119/61.5/148, but no 129, emerging as their HD sat).
Kingdome, under their 2 year warranty, sent me a newly available upgraded tuner and a "sat software upload box", which I just installed and used to update my sat SW.
The result is my sat receiver is "aware" of 119,110 and 129(hd) sats on "boot-up"
and when I select a channel that requires a different sat than the one currently locked, the Trac King acquires the next sat with ~5 second delay.
It works great!
