Looking for recommendations for a microphone for interviews!

I just filmed an interview with 2 people, and mic'd both of them up with 2 DR10l's. It was fine and all, but I feel it could be easier in post to just have one single mic/file.

I'm not ready to purchase just yet, but maybe in the next couple of weeks. Hoping to find something less than $400! I know that might not be ideal, but hey, that's what I've got to work with.

I was going to buy the DJI mic's, but I feel they don't look as professional in well staged interviews. Unless there's a way around that.

Thanks so much!
