I've since reformed my "critically accurate recommending ways" here. I've apparently missed the question - running off on my own tangent. To that, I apologize.
Good center speakers: NHT VS2, NHT Audio Center 2, Paradigm Pro Studio, Mcintosh HT-1, Infinity MTS Center, Wilson Watch, B&W Nautilus HTM2, KEF Reference 202/2C & C200, Meridian DSP7000c ($?) Dynaudio Evidence ref center (a little pricey).
If I've left any good candidates out, I'm just a little fuzzy on some candidates at the moment. But the above should "get you buy" otherwise.
