Is there a thumbnail site you can surf and see themes?

Are there a couple of basic compliant and validated themes for latest versions of WOrdpress you can use to build a top notch WP site?

Is there a location where you can review theme thumbnails?

Something along the line of themes that will work with current WP releases?

I found the listing of WP themes compatible with 2.7 in docs.

1. It is time consuming clicking all those links.

2. THen you have to do further clickons to see the theme.

3. Then when DL you have to know what you’re getting.

I realize the themes are free and that’s nice, but I still think better information that is better presented has to be available.
