Have a look there is it will give you some ideas. If you want to spent as little as possible then the D40 is a good bet. As for the D60 not read much on it but it still isn't that great. You would be as well looking at some other options such as: Canon Rebel XS/XSi/XTi or if you look used a Canon 40D or a Nikon D80 (reviews of all can be found either here:

At the end of the day go into a shop and have a feel/test of the cameras and see which you like the best and then make a decision from there. You'll also need to remember that the more you spent on the body the less you can spent on the lenses.
Also take a look here as it is a good summary:
