Let me start off by saying that I love my DTV service, and I love my TiVo service. I currently have a SD DTiVo receiver. I am guessing it is the R10 version from what I have been reading here. I want to make the switch to HD. I am not interested in any sort of hacks, and I want 1 box that handles both TiVo and DTV. Should I get the HR-250 off eBay? Is there a better place to buy them? Is there a better version to buy? Will this box be obsolete the minute I buy it? Is there a certain brand I should stay away from? Thank you for your help!
