I would suggest getting an adaptor with AF confirm circuitry otherwise you will be limited to focusing visually using the screen alone. Unlike the Nikon bodies the Canon AF system doesn't offer focus confirmation via the AF system unless it is fooled into thinking an EF lens is fitted... Manual focusing using the screen is possible but the AF screens are not really designed for this sort of focusing and it can get very tricky with slow lenses. Oh and it's best to focus with the lens wide open first and then close down to the desired stop for metering

I would also suggest getting 2 adaptors as having only one can make lens changing cumbersome. You have to take off the current lens, place the body cap on the camera, take the adaptor off the lens, remove the rear cap from the new lens, put the adaptor on, put the rear cap on the previous lens and put it away, take off the body cap and mount the new lens... Believe me this is a pain. Having a second adaptor would at least allow the next lens to have the adaptor already fitted at leisure and allow much more rapid changing - old lens off new lens on and no messing with body caps...

IMO I think you'd be better off looking for a used D200 which will meter in 2 modes (A and M) and may be OK flash wise as the AI coupling ring tells the camera what the aperture is.

I do have an F/EF adaptor for my Canons but TBH I'm seriously considering getting a used Nikon body (even if it's one that can't meter) as I find using them on the Canon a bit too much of a pain and my eyes are not so hot on the manual focusing front so the using the AF system for focus confirm may be useful.
