Well, you don't indicate what kind of main speakers you have, nor how much money you are willing to spend on the surrounds, so my suggestions may be a "shot in the dark". I will assume for the sake of discussion that you want wall-mounted surround speakers, rather than floor-standers.
Of the surround speakers that I have heard, there are three that have particularly impressed me:
1. M&K SS-150 dipole/tripole surrounds (about $1200 / pr)
2. Snell surround speaker (don't remember the model designation, but they sell for about $1500 / pair).
3. The third speaker you may want to add to your audition list is the new Snell ceiling-mounted "PowerPoint". It's gotten very positive comments from a few of the HT equipment reviewers. The fact that it is ceiling-mounted may be a plus or minus, depending on your room setup.
