Marantz or Denon receiver ?


Hi yall, I was wondering what was the best receiver between the Denon avr3300, Marantz sr-8000 and Denon avr4800. Here is my thought: I wanted to buy the Denon avr3300 online for $660 (Best online price). I discover lately that this receiver have certain problems with overheating and shutdown. I looked at the price of my local dealer and it was $1000 (big differences!). For this price, I was wondering if it was worth spending more money for either the Marantz sr-8000 ($1340 at my local store) or the Denon avr4800 ($1370 listed online) ??? I am afraid to buy a product online and do not have any warranty when problems arise. I try to locate the marantz sr-8000 online, but it is difficult to find it for a good price. Can someone has an idea or suggestions in this mess? I appreciate your feedback.

Yamaha RX-V1 or the Denon AVR-4800 they are very similar I actually prefer the Yamaha myself because of previous purchases. My dealer sells both and says its a toss up. How about Sunfires Theater Grande II?
You might also want to check out the Nakamichi AV10; I listened to the various Denon, Marantz, and Harmon Kardon receivers at around 1-1.5K and this was (to my ears) the best of the bunch. You should be able to get a new one for between $900-1000. Also, check out the reviews on www.audioreview.com.
What a timely post as I am currently considering the Morantz SR-7000 and the Denon AVR-3300 for 50/50 HT/Music. Seems to me the Denon offer more for less $. But I haven't heard it yet and the Morantz may still hold the high groung as far as sound quality.
