Not to introduce more confusion by adding more choices, but have you scoured craigslist in your area yet? You'd be surprised at the great deals that came along.
I got a 1610 for $125 2 weeks ago which I thought was a good deal, but just two days ago I replaced it with a Denon 2310 for $110! With the savings, I just bought an appletv so I could have airplay.
That may end up being your best bang for buck solution?
Of course, if you have to use your $75 best buy bucks or want the security of knowing you can return it in 30 days no questions asked and want things new, I understand this may not be an option for you.
