Joe,
I would say give the D-Link a try if that's the way you are leaning. Referring to the DIR-655 specifically, there must be a reason it received rave reviews - and truth be told I wanted it to work as it had some really cool features I would have found useful. However both my NAS and my Sonos controller were just quirky on wireless with it. Replacing with the Linksys cured my issues. But maybe the D-Link will work fine for you? Peter seems fine with his judging by his post.
