OM-2 (365 mono #269)

I'm searching for a 35mm film camera at the moment to take to Truck (a local music festival) in the summer.  I really don't fancy taking my digital in case I lose it or break it and so a film camera would be both fun and quirky.  Just right for a music festival, I think!

I have an Olympus OM-2 on test from a friend at work.  Film is loaded.  I just need something to practice on now.  I tell you what, all of the manual knobs and levers make it a more testing job.  I must give credit to any photographer from the days before auto-exposure, auto-focus etc.

Anyone have/had an OM-2 or have any tips on a cheap-ish 35mm SLR that I could look out for.  Anyone recommend a 35mm film type?
