Most people are correct in that most good DSLRs are around 1000. However, Panasonic makes some great micro 4/3 for under 1000. Also, a GOPRO is a good alternative as well.

As for mics is depends on the place, you are recording. Room acoustics are as important as the mic you are using. If you don't have a sound treated room, a dynamic mic is the best, unless you can use Nvidia broadcast (can only be used with Nvidia RXT cards.) If you have a computer with Nvidia RXT card, then I recommend Elgato wave mic. If not, then the Beacn mic is great as well.

80 and 85 have to do with which market is sold in.

Here's the g85 on Amazon (USA)

I think besides the market origin, the 85 comes setup with NTSC and the 80 had PAL.

I believe they can be changed regardless. But I may be wrong.
