Click on the link to download the Mirror Blends python script.
Made a small tutorial on how to install and use, if you need the help.
Steps:
1~ Copy script to Maya script folder.
2~ Run Maya... Copy, Paste to Script Editor (python tab)
import MirrorBlends
reload (MirrorBlends)
MirrorBlends.gui()
EDIT: Just keep the three lines of code... You'll get the error on a regular basis, but it should still work... without fail.
3~ Execute script (pretty self explanatory pop up window)
