Receiver?

I’ve been a Directv customer since the beginning, when there were 2 separate services (USSB) and I currently have a Genie HR54/500 500gigs which I’ve had since it came out, I only use 1 tv for Directv but enjoy the freedom of using the DVR. But it seems I’ve just about reached the end of the receivers life as I keep having to unplug and restart as it sometimes freezes and sometimes I can’t use the remote, at least a few times a day.

  My question is should I continue with another Genie or is there something newer, better out there? Sure I’d love to get a free genie but I’m not sure I want to sign another 2 year service contract. Any thoughts you could give I’d appreciate.
