What are midi controllers for iPad that works with DJay and has mic input?

Just asking for future purchase. I want to buy a new midi controller that works for DJay 2 and has microphone function. Pls help! Thanks

I use Numark’s idj Pro controller and the mic input is very nice. Has its own volume control for the mic which is very sensitive. Good quality from $10-$20 mics from Target and $300 wireless mic from Guitar Center. Idj Pro ($180 to $250 used on Craigslist and eBay). New is about $400 probably. I recommend used – first controller lasted me 2 years before crossfader became less sensitive. On my second board. Paid $180 each time. Hope this helps.
