I thought from others comments that the V9 Prime was no longer available. You were wise to grab a few extra. A quick check online shows I could still get one delivered to my home
from China for US$48. I'd pay that if still available.
For products like these, I don't care if there is any "support". If the unit works, then I rarely seek support. It's a gamble I suppose if it fails out of the box, but what choice do you have? I would consider a receiver from Rick's instead but getting something across the U.S. border nowadays is probably as tough as from China. I source from Canada if possible but an FTA satellite receiver may be tough to find here.
