David, that's a very kind offer which i may take you up on if I can't find a cheap one locally or on ebay.
Bikepacker, cheers for the recommendation of the Autocord. Looks the business and there are a couple on ebay at the moment. Might try and get a hold of one of those in the future. They certainly seem to have their fans.
I think I'm after something a little less 'polished' though at the moment, if you know what I mean. The images I've seen from the Autocord look a bit good. It's that lo-fi look I'm after, where the crappiness of the camera plays its part in the feel of the photo too, which is why the Holga (and to a certain extent the Lubitel) would be ideal.
Decision, decisions...
