Alan,
Last fall I purchased thirty rolls of film direct from Astrum: 10 rolls each of the 100, 200, and 400 speed Astrum Foto 35mm films. All three are very good, but handling the 400 ASA film is a bit tedious, since its on extremely thin polyester base. I find it a challenge to get it into neg sleeves. On the other hand, it dries very flat and it a please to scan/print from. It seems all the Astrum films are traditional cubic grain films, so if you like those (think Tri-X, etc) then the Astrum Foto films should work for you. The 100 ASA Foto is surprisingly sharp and fine-grained. Mind you it is quite contrasty, so make a note. One thing I don't love about Astrum's product is that they use very cheap plastic bulk load type cassettes. They come apart a bit too easily, IMO, but they are usable. Here is a sample from the Foto 100 film:
The Svema films are all outdated, since Svema went out of business circa 2000. (Astrum bought the facility and restarted under the Astrum brand) I've used the Tasma NK-2 and its interesting film. However, I bought it from the Film Photography Project store, and they sell 20 frame rolls for something like $8.00, which I think is steep, especially considering the fact that every roll I've shot has light leak contamination from the cassette.
