I was on E's website the other day looking at my account and went into the screen to see what offers are available to me and I noticed that like my 811 offer I could get the 510 for 5 dollars a month, if I was reading it right. I tried looking for reviews on the site here but could'nt really find anything conclusive on it, so my ?, is this a descent DVR for 5 bucks a month and would it work with my system without adding any cables or anything, I have Dish 500 and two rooms hooked up my living room has the 811 and my bedroom where I would like to put the 510 has the 301, so can I just unplug the 301 and plug in the 510 and are there other monthly charges with this unit? Thanks for the help!!
