I shot a test roll of Neopan CN in 35mm a few weeks ago, got it developed, printed and scanned in Asda for less than a fiver because it uses C-41 processing (ie colour print process). The scans are very low rent and have a pink tinge to them, but the negs and prints(at 7x5") are very good.
If you want a cheaper option then its well worth a try - film, develop and print under £7 for 36 exposures !
I've used Ilford Delta in 120 film - nice film, large tolerance for exposure.
