EmuELEC : a controller advise?

I’m looking a for a good budget remote control for playing with EmuELEC.
I want something robust and wireless and also trouble-free (automatic setup, good support, etc.)
Any recommandation ?

I use, and can recommend GameSir G3s. It works with WiFi dongle (included) and with most build in or USB-BT Bluetooth adapters. Very good build and response. Available from here

Thanks, I cannot find any available, I guess a new model replaced this one.
