I THINK the denks, seiberts, TVs, and baaders are the only self-centering ones. Since Ive owned 5 or 6 pairs before I arrived at my "preferred set-up" (denks with 24 pans), my advices is to buy a used seibert black night and try it out. I think you can get them used cheap (like under 200) and they are WORTH it. Some of the burgess and other celestron/etc units are just not up to the quality of the smaller US manufacturers.
What king of EPs are you planning to use?
