Is the only difference between the 43tx and the 45tx the manual instead of auto MCAAC? And for the price of the 43tx, what other recievers out there are comparable to it? Would you suggest a 43tx in that price range? ($600-$800) 35% music/65% dvd or tv. If it helps, a new dvd player is in my future, but it won't be anything super fancy, just something to get me through until I get a real job and not an internship. Basically, I am just looking for a list of recievers comparable to the 43tx to go audition.
