Cool thanks, I guess EBay is probably the best place?
If you go ebay, you need to do a lot of homework to get one ...
You'll want to get the numbers off the recvr you want and call D* and verify that it is a recvr that is Owned and not Leased, as leased ones need to be returned and are often put up on ebay.
Even if they say they are new, doesn't mean they aren't already leased.
You would be happier with a HR24 ..., if you need to get an older one, I would go all the way back to the HR20-700's they were pretty reliable and has a OTA tuner built in.
