I quite like Design Meltdown: http://www.designmeltdown.com/archive.aspx
It categorizes websites by colour style, website type, design theme and so on.
It's a really handy resource when you are looking for inspiration.
Design Meltdown is good! Also be sure to subscribe to the blog at Smashing Magazine: http://www.smashingmagazine.com/. Awesome articles and they periodically do "Top 100..." style posts. You can run a search through their huge archive for something like: "Best E-commerce Design" and get a ton of great articles and galleries. Get inspired then go make something great!
I find that web design award sites are good places to get inspiration. I have no artistic ability. I lack the imagination and skill to make a pretty website. I can do basic business type websites. But I will never do anything artistic. Here's my list of inspiration sites.
