Why bother with a Film SLR? Because there's nothing quite like the fact that you've only got 24 exposures, and its going to cost you £8 to get them printed, to focus your concentration on getting your composition and light correct - unlike a digital where you can happily snap hundreds of photos for no real cost.
So the cameras you see in the video are the SRT 101 - a fully manual, tank of a camera, that is worth buying but just be aware that you can't buy the exact batteries anymore and have to make a few mods.
My favourite is the lighter X-300s, which offers aperture priority shooting as well as fully manual, and this is the one I'll be carrying in my camera bag along-side my digital Fujifilm S5700.
Where to buy? I'd search your local car boot or garage sales or eBay - hold out for a really nice one with preferably a bag and selection of lenses. I got each of mine for less than a tenner, and I love 'em.
Here's my post on the first shots out of the SRT 101.
