This is one time I’m going to recommend you not take John’s advice. He means well and I always appreciate his very frugal advice. He is also the first person I go to for just about anything A/V related. However, for this particular topic, the 3808 is heads and tails better than the 661. I’ve had both and still have the 3808. I can (and will) buy anything I want. The 3808 does everything I want and more. I have had ZERO interest in replacing it, which is a remarkable achievement when considering how often I waste money on crap I don’t need. The 661 was OK, but it’s not in the same league as the 3808, not even in the same sport as far as I’m concerned. The 4808 is a waste of money in my opinion. If you are going to go above the 3808, go with the 5308.
