I still had a HR10-250 connected up I used for SD in a bedroom. However, it completely went out today. DirecTV is going to replace it with a leased (I had owned mine) HD DVR refurbished unit for $20. However, I would like 3D capability now too. Am I likely to get a HR20 that doesn't do 3D? Should I cancel the swap and just replace the receiver myself with a HR24 from Weak Knees? I'm a bit worried still having a HR10 they think I have an antenna and would then need a HR20 for OTA. However, do they really still have HR20s around to send out?
