In European countries and even china- LPIC (
http://lpi.org) too is famous.The plus point is LPIC is vendor neutral and though it is a write only exam taken in pearsonvue authorised or prometric centres,It is designed by inputs from all major Linux players.even RedHat too.also they cover pkg managers also very well esp debian dpkg and redhat rpm.also LPIC is cheaper
afaik(around Rs5000?!) and u get a full certification on Linux including networking too,while RHCE is basically a networking certification although their Practical only exam is well created(takes A DaY!)
