Tileable Wood Textures?

Does anyone have a good source for tileable fairly high-res wood textures? (Finished wood, not tree bark or flooring) I don’t mind paying, although you can’t beat free. I have found plenty that are just photos and don’t tile well.

for renderings I often get wood images from laminate websites, here are some good ones

www.formica.com
www.wilsonart.com
www.laminart.com
www.nevamar.com

search under woodgrains and you should be able to find some good squares. otherwise you can always find a website that you like which uses woodgrains and ask the webmaster where they got it. most people will be cool and let you know. you can also look here:
