Any sub option other than monthly for 500gb Roamio OTA?

Has anyone ever been offered anything other than the $14.99 monthly sub on the original 500gb Roamio OTA model? I'm aware they offered the OTA close out deal of $299 with "all in" sub when the BOLT came out for a limited time but I'm interested if anyone has had any luck getting an "all in" offer or reduced monthly fee if they threatened to cancel etc. I bought a 500gb OTA model for some friends right before TiVo began offering the 1GB 'all in" OTA model (which I probably would have bought instead). Everything I've seen from TiVo is they won't offer any other option for that model. They are committed for another 8 months of the one year commitment right now but I'm curious if we call to cancel at the end of that if we have any hope of negotiating anything different.
