Re: Panasonic AF100....Canon or Nikon lenses?

All your posts are really a big help.
I got another tricky question for you.

Which adaptors would you suggest for the following lenses. I just found them very cheap here in Mexico. And do you think that they are worth buying it? I am looking for some adaptors which are good but quite cheap. I believe in the words of Uli.

Here they are:
Canon FD, 50mm, 1,4
Canon FD, 28-70, 3,5 (is it posible to use that zoom?)
Nikkor, 24mm, 2,8
MC Rokkor, PF, 85mm, 1,7

How do you select your adaptors? Is there any good list you found?
Thank you so much!
