I have really wanted to get into emulating on the go and can't find a controller that fits the bill. I want something that can hold my Nexus 5 up, charge it, and is right around $50. The Moga Controllers seem the best, but they are expensive, the models are confusing to me and from what I have read, don't particularly work well with emulators. They also look pretty cheap. Any ideas? I would basically be emulating everything under the sun from SNES to N64 to PSX to old Atari systems.

Thanks!
