The first one, you have to check regularly as they will have some wicked deals regularly. The second one sells refurbished units. They are an authorized reseller of every brand they sell and their customer service are next to perfect, so is the first vendor for that matter
In that price range, I would favor Denon and Onkyo. If you look at the second vendor, they have a Denon AVR1612 for less than $200. That would be my first choice.
Awesome guys that's exactly what I was looking for. I was shocked at what the denon had for its price. I've ordered from the second vendor before and had a great experience not sure why I spaces them this time. Ordering now!
