That's a good "master". I recommend to get also some inexpensive off-camera "slaves" to allow more creative lighting.
I have three of these and I'm very happy with them (for $41 you can't go wrong). Just position them to some nice angle, set to optical slave mode (+ adjust the desired amount of light) and shoot with your current flash: When the in-camera flash is fired the slaves are automatically triggered, giving you the desired amount of light from desired directions.
Here's good place to start reading about your soon-to-be addiction: strobism.
Back on topic: I got Thrunite T30 (For $34.95 it was a steal! A very nice light with moonlight mode and nice UI), Romisen RC-C3 NW (Nice small light with perfect tint, recommended. But has unbelievably ringy beam - especially for a OP reflector!), and replacement driver for my SWM R01A (Special thanks to Sunwayman & Battery Junction for delivering me one!)
