Ignition switches

Can anyone suggest a good place for ignition switches? I have a 1967 and have installed 3 switches from various auto parts stores (all parts from China) and they have all failed in some way or another, either shorted out or completely came apart. Does anyone sale a GOOD one made of quality parts?
 
Sorry.....I got my new switch off of Ebay, it's a Motorcraft in the original box and is stamped on the switch "Ford" the quality of this switch is hands down superior from the parts store switches, everything about it including the crimp is very sound. Installed lastnight and works like a champ. The key even feels better in all positions. i payed $30....but worth it.
