I've been watching prices of dish receivers at some online retailers and the prices have gone down dramatically. I have 2 522's (running in single mode). The 612s are going for $99. Hoppers for 199. Is there some new receiver about to be released? I really dont care about HD. I would like the extra storage space the 612 offers and to get rid of the one leased receiver i have now. Would it be worth it? I have read about the 612 being flaky-- has it been fixed?
