Script question

I am trying to write a script to check the STIG our unix boxes. I want to put in checks to determine if certain files or directories are there. For example:

If /opt/SUNWexplo exists
echo "Sun Explorer exists"
else
echo "Sun Explorer is not installed"

I am sure I could write something like

ls -ld /opt/SUNWexplo
if $? = 0
echo "Sun Explorer exists"
else
echo "Sun Explorer is not installed".

however I am trying to find a more efficient way to do this. Any help is appreciated. Looking for something that works on both directories or files.

Thanks,
Robert
