Received a Yamaha HTR-6150 for Christmas...

[Bud2003]

My wonderful g/f took it upon herself to purchase a receiver for me for Christmas. After doing some researching, I see that the HTR-6150 has quite a few missing features that the 6160/663 has for a very comparable price.

Now she purchased the receiver through dell.com on 11/24 and being that I didn't open the gift until 12/25 they will not do an exchange or return for me. The item was opened after the "21 day product satisfaction return policy" expired and she ordered the product 4 days before the extended holiday return policy kicked in (11/28). Being that Dell has a bunch of a-holes for customer service reps, they won't even budge, even though between my g/f and I we've spent over $10,000 with Dell in the past 3 years.

So, I'm in a place where I'm not confident I have a decent enough receiver for my money, yet I am stuck with it. Any professional opinions on how the 6150 really compares to the 6160? I have done the comparisons and I see that it does not decode everything that the 6160 does. Are the missing features enough to worry myself about selling the receiver on eBay or Craigslist so that I can get the slightly higher model?
