Also look at Time ATAC pedals. They appear to have all the positive things that Eggbeaters offer, though with a little bit more weight, but with bearings that last much longer.
I have a pair of ATAC Aliums that have served for 10 years on my singlespeed, and are still on their original bearings and bushings (greased every couple of years), but the engagement rods/loops are starting to look a little worn.
