You really need to consider not ceiling mounting your front three. The angles do not work well for clarity and dispersion.
Having said that, as far as in ceiling speakers go, there are a number of good options. I like the RSLs, but your budget can do better. The clarity and fullness of my Paradigms are better than the RSLs, though they do cost a significant amount more.
If you can get your front three to on wall, in wall, or merely mounted bookshelves, that will sound better with the right angle and dispersion.
