I've got the relatively cheap-o Sidi Rampa's now although they are lighter than the Shimano, better fit, way better for riding, they are tricky when off the bike exactly as noted above.
I had shimanos as well...they lasted forever...they were the boot ones that kinna look like sidis...lasted me 7 years or so...they just started to fall apart last year.
