Well, I have a bit more understanding of what's involved in the upgrade, 2k Is not out of line for the automatic dish
For a fixed install (or a tripod install) the job is change out the antenna, point it, done.
But the automatic roof tops the bigger antenna takes a different motor, a stronger mount, and a different controller
Quite a bit of modification Of course if you have the best system Motosat came out with before the change.. Then it's a bit simpler. but still a major job.
Software updates happen because they rushed to market at the request of their users.. There is an old adage
Do not buy anything till revision 3
Applies
By the way.. Rumor on the nets is that DIRECTV is going to release yet another new antenna soon.. Though the current 5-lnb will continue to work.. The new antenna is smaller... You might wish to wait
