Sorry for the abrupt answer, but I'll stick by my guns here...
That camera is a good little camera, from a respected make, that has done all its depreciating. You'll be able to give film a try, run a few rolls through it, an if you don't like using film, it'll sell easily enough, probably for near enough what you paid. As explained, colour film processed on the high street/supermarket costs best part of a fiver a roll - call it 14p a shutter press. Black and white is dearer - chromogenic (C41) B&W film is maybe 3.50 a roll, plus £2-£3 processing... Proper B&W is dearer still, if you pay for developing - say £7 for dev and scan, and a couple of quid for the film itself. Of course, it's dirt cheap if you process it yourself, but you have a outlay on hardware and cemicals of maybe the same as the camera above, plus a scanner.
Top and bottom of it is film isn't cheap - it can be affordable if you have access to university darkrooms/chemicals say, but there is always a certain capital outlay if you're going to use it properly. Of course, if you just want to TRY film, borrow a camera from someone you know, and shoot a couple of rolls. Bash 'em through Tesco's and they'll rush you a fiver a roll, so a tenner will let you know if it's for you.
For me, a couple of rolls a week is maybe a tenner's worth - covers pretty much all my non-work shooting needs, and is cheaper than lunch at the pub once a week :shrug:
it's crazy to have different brands 35mm & digital.
