Predesigned skins or css for asp.net menus

I'm just tossing together some websites for various clients and i was wondering if there was a place where people had uploaded various stylesheets or skin files for things like asp.net menu objects, grid views, etc...  All to often I find myself spending hours and hours trying to get some darn menu or list to look pretty when I really would be perfectly happy if I just had some generic ones to choose from.  Kind of like in MS Access, how you can choose from various report templates and then alter them to suit your own needs.

anyone?
