My six standard answers:

1. Buy a good used one, rather than new.
2. HW35/80/85/95/98/99.
3. Diana 31/34/36/38.
4. FWB Sport.
5. Webley Omega, Tomahawk, or Longbow.
6. See 4 and 5.

2 and 3 are fine, too. Actually, option 2 may be best. Matter of opinion.

Try to find a club or a good shop when you can check a few out. Fit and feel are vitally important, and can only be judged in person.
