Recently, I installed a 1.2 meter Geosat on the same DG380 that I purchased in 2008. So far, the DG380 has been able to handle turning the Geosat down to 15West.
I still do not think the DG380 is as good as the HH120 for turning a 1.2 meter dish, but so far the DG380 has been able to handle the 1.2 meter dish OK. We have not had any snow or ice yet, and I do not know how well the DG380 will turn the dish when it gets some extra weight on it. TheDG380 seems a bit stronger than the 9120 motor. I have had the same dish and lnb installed on the Powermax 9120 and the DG380. EB
