Hi Alex
http://karups.com has many tgp2 hosted galleries they use for there sites. The galleries have good content and look pretty nice also. And they are Tgp2 compliante.
Epic cash use to have hosted Tgp2 galleries, but not sure if they still do. If they do be sure they are tgp2 compliante before you use them. They did have some that were not compliant.
Naughty's program, I think its
http://naughtycash.com did have some also.
Hope this helps
Oz
