I used Eggbeater cleats on my Specialized m020 Mtn shoes (el cheapo). They worked pretty good. I would get a bit of soreness on the bottom of my foot after 80 - 90 miles due to the sole not being stiff enough but they worked pretty good. I just had to replace them because the seams were coming unsewn, I had about 5000 miles on them. They worked awsome for commuting' as they gave good grip when putting a foot down at the lights.
