the 985 is actually two generations old now (995 and 997 being the replacements). it is "only" a 6.1 channel receiver as the newer ones are 7.1.
the main advantages to using Sony are generally matching to your TV to use a single remote and (in my expereince anyway) that they last forever.
the disadvantges would be that this model was considered by the posts I found to be be very difficult to set up and that the sound quality is merely very good but not great. maybe someday, Sony will hire people who speak English to write their manuals. I have found that many functions are easy to do, it's just the translation into English was done so very poorly that it seemed much more difficult.
I have a 995 (about 2 years old) and a 915 (about 15 years old), neither of which have every given me any problems (unlike a pair of Kenwoods that were not very reliable).
At that price, the deal you have will be pretty tough to beat (if I do my math right, it's on the order of $ 225 to 250 USD). You might find an Onkyo 501 (also "last year's model") on closeout for a similar price, but that would be the only real competition. The same item in the US is currently retailing for about $ 400 on shopping.com.
