I don't disagree with you about the value. Its just not for me.
I'm much more comfortable purchasing something assembled and reviewed. I'm a clutz with tools, and really don't have the extra time for assembly.
If something doesn't sound right or is unsatisfactory, I'll know I'm not the culprit. That is worth extra money to me.
Now if you have recommendations to go with that receiver for a sub/center/bookshelf I'd love to hear them!
