It's debatable whether buying a cheap module from eBay that works at 110-240V and has a bare wire that you actually touch is a good idea.
This one isn't too bad if you trust a non class Y capacitor between you and a bad time.
The circuitry is OK and has a degree of hackability for playing about with resistor values. There is no RF filtering on this potentially noisy phase angle control dimmer.
