Just last night i was looking into the options with Holgas and 120 film (got excited when i saw the Holga WPC (wide angle pinhole camera - shooting 12x6)) ... the "running costs" were a bit of a put off.  Although developing your own negatives and buying a scanner would reduce that to just film purchase and chemistry... but then there are costs involved in that too... maybe if i sell one of my lenses i never use... 

As for old camera's i have a kodak brownie back home i have never used - maybe i should give it a go before i look at getting a holga.
