I checked out where some demo locations were listed in NC, and nothing I found was remotely close.
Also...I'm getting quite a few suggestions regarding the same issue, and that's to get a bookshelf center for vertical placement rather than a horizontal one, as this can make the center sound more appropriate. I've read ideally that really getting 3 of the same fronts (M60s or M80s) is best...however that would make it quite awkward to position given my space and setup. How much difference can this really make? I see this is a big debatable issue with lots of opinions out there on it.
