I just got my 1000.4 here in SD and 77 comes in in the low 20s, 61.5 in the mid 30s and I haven't had any issues. Thankfully it doesn't rain here, and while I don't get any signal from 72.7, it seems to be working OK. I have received some 'signal loss' errors, but its working. I am counting the days until the new satellites go up, though. Kinda like when I lived in Seattle and 129 would drop every 30 mins, even with the large pan dish.

I don't think it would benefit you at all on the west coast to use a eastern arc dish. You would be better off using a dish 1000.2 , especially since the 129 sat is new and working great now.
