Permanent node lists

Are there any lists out there of permanent nodes to add to my list? When I do a search for a file, I've gottent basically the same results for months. I'm wondering if I'm always hitting the same small group. It seems like there should be more variety over time. Right now I'm pointing to router.limewire.com.

Thanks in advance for any lists you guys may have.

This is a list of mine
