if you are recording for youtube it might be better to use a rubber dome keyboard over mechanical to avoid noise. just a thought.
also, without you telling us a budget we do not how what you consider cheap.
the ducky zero is a good fairly basic no frills mechanical available as low as $80. the hyperxcloud is a good budget headset for $80
if you're looking to make good youtube videos however you might want to consider using a good desktop microphone on a boom... if you're serious about it. the hxc is fine for just fooling around and figuring out if you like it or not.
