In response to Sil,"I wish there was 800 delta" I think most people would agree that delta 3200 has a nominal EFS of 800 in most developers. EFS= effective film speed(posted 8183 days ago)On the subject of film for P&S cameras follow a few simple steps
a) If you are uninvolved in the process completely start with kodak chromagenic films, T400cn and they also sell a consumer film that should be just as good (B&W+?) this should give the best results from a mini lab.
b) If you're printing your own work but don't develop film try ilford xp2 super. This is easier to work with in a conventional B&W darkroom. c) If you want to develop your own film try a fast (400 ISO) older film HP5+ Tri-X etc in the manufacturers recomended developer and then start experimenting with different emulsions/developer combinations. Forums such as this one are a good source for inspiration regarding chemistry and film.
d) buy lots of film and shoot shoot shoot, never go without shooting for too long.
