Thx Snipes! I'm leaning towards the 50d as well since it will feel more special. The 40d is about 77k euro and the M50d is 88k ie both are expensive. But over three years I think the M50d will get a better value on the second hand market.
There is no way to try it here since they are only made to order but I did try the 550d and liked the feeling. The 550d of course is way faster on paper due to less weight and lower centre of gravity.
Have you tried the 50i and if so how does it compare in feel to the 50d? I could probably test drive a used 50i.
