If I understand correctly, the DBK monochrome camera (640 x 480) needs filters to take pictures in colour. Filters are quite expensive. Wouldn't I then be better off bying a higher definition DBK colour camera (1280 x 960)?
All this is new to me . Apologies if my question is naive.

The DMK is monochrome, the DBK is colour. Those Jupiter shots are with the DBK colour camera, no filters required.
I have used both the DMK and the DBK, and am not convinced you get a noticeably better result for planetary with the DMK mono + filters vs the one-shot-colour DBK.
In theory the higher resolution camera would be better, but the chip is bigger, so you only end up using less than the 640x480 anyway as the image doesn't fill the chip.
For planetary the DBK21 is easily the best choice in that price-range for planetary work. The higher resolution cameras are good for the Sun (with appropriate solar filters of course) and the Moon.
There are high resolution, fast frame rate, small chip cameras out there, but we are talking in the thousands of dollars.
You can see by those Jupiter shots that the colour DBK21 can deliver the goods, the rest is down to your optics, the seeing and your processing.
