In the film cameras, yes. spend on lenses.
Because you can always change the film that goes into the camera.
If you need higher resolution and less grain, use low ASA film.
Not so long ago, you could choose from ASA 25 to ASA 3200 or higher You can use B+W, colour negative, slides.
In a digital SLR, the "film" is fixed.
The digital sensor and the electronics that work with it
as a system cannot be changed by the consumer.
That is why no matter how well built it is, if a "pro" camera of a bygone age has only very low xx megapixels, slow autofocus sensors, lousy digital sensors, outdated electronics, poor image handling software/hardware, it will be junked; in favour of the latest digital SLR.
But actually I am aware that many have a 20D on their hands and were caught off guard by the rapid introduction of the 30D at the recent IT show.
If CS members' general opinion is that it is better to buy a used 20D rather than the new 30D, then it will be good for them. Privately they may say, [Whew! Lucky I could sell it off. ]
The one who encouraged you to buy a used 20D instead of a 30D, may then take your money from the sale and rush off immediately to buy a 30D --- quietly of course. :bsmilie:
