Replying to External Recorder for the fs700?

Just seeing what people on here use for the fs700, or if you guys actually use the avchd codec.

I'm in the market for an external recorder, but it doesn't have to be able to record 4k. I don't want the huge panasonic recorder, and I've seen the Q7 but it's pretty pricey. I've heard of people using the Atomos Ninja? Is there anything else anyone could recommend that will record a better codec? Also, has anyone tried the atoms shogun? I heard with the new firmware update its compatible with the fs700, anyone tried this out?


Thanks!
