Let me gush over two of my favorites:
Cable Organizer, a big site, has everything but the - sink. Overkill for most of our needs. No nonsense approach to selling to web-savvy tech buyers. Excellent product info provided.

Gentleman's Emporium, a small site, sells historical clothing. I was blown away when the owner, a non techie, told me he built it himself. Great features and gorgeous design that's perfect for the subject matter.

As a non-pro, for all I know these two may be junk "under the hood" but both impress the hell out of me.
Anyone else have an All Time Favorite SS site?
