I did it. I ordered a Holga 135BC!

I've been shooting with my Canon 450D for the last 3 years and haven't used film for quite a while. I'm just wondering if you guys can point me in the right direction film wise for my little holga friend? I'm wanting to get stuck into some black and white stuff, and I won't be processing it myself, although I'd love to do that someday, loved being in the dark room when I was studying....

Have you got any tips for me when I'm looking for some film? And what are your thoughts on expired film? I saw some on ebay the other day, a mixed bag including film expired from 1996, would film this old really still be ok?

Looking forward to hearing from you
