If Print:
- Fuji Superia 100 is good, readily availiable and cheap
- Kodak Ektar is mean't to be quite good but I have not used it yet and its more than the Superia
- Portra 160VC is good, very fine grained and brightly coloured. Bit more expensive though.
If Transparency:
- Fuji Sensia 100 is quite cheap and a generally good film.
- Kodak Elite Chrome 100 Extra Colour (EBX) is very good in my experience. Fine grained and saturated colours but skin tones are still quite nice.
- Agfa Precisia 100 is supposed to be good as a general purpose slide film. I have not tried it yet, its on my list but pictures using it on Flikr look quite nice
The best place to get Precisia is discount films direct. They do it both with a processing mailer and without.
7dayshop still have stocks of Reala BTW as of last Thursday. Thats another nice print film, very natural colours and sharp but unfortunately its no longer manufactured in 35mm, only 120.
Hope this helps
