One Of These Things Is Not Like Others
In the case of the Canon 250 shot magazine the camera you will need is a one of the F1 film cameras with a 250-shot reporter back. None for sale new, of course, and very few made when they were new in 1971, but you can always haunt ebay or Boris...You'll need a 100' roll of film to charge it, another 250 shot cartridge to receive the film, and a darkroom to get the stuff spooled up. It might be a good idea to go speak to the pro lab to see if their processing machine will cope with the length of the film you use. All up, figure about $1800 minimum for your 250 shots. Plus negative sleeves...
The 35mm cassettes will go in any 35mm camera so you might luck out there. Pick up an old compact for $ 80 and add the film...$ 90...and the processing...$ 125...well you'll be a lot better off for your 250 negatives. You'll only spend $ 295 for negatives.
Of course if you elect to get a new small compact camera and the 8 GB card you can also set 250 shots for about $ 209...but you can keep on snapping after that - the card will hold a lot more shots. They'll be in colour, but most computers will let you see them in black and white and you can even invert the image files if you are a freak for negatives.
I haven't costed out two and a half tablets of artist-quality drawing paper and a handful of pencils but I'll bet it is about the same price...if you draw in negative you'll need more pencils.
Note: the 250 shot magazine is a second hand item, but the Hoodman memory cards and the Kodak T-Max film are both new and readily available in-store or on our online shop.
