I think not. The G3 kit from Sennheiser is a very good starting point for a lav kit. You can go higher but start at this price point. First the sound is sweeter and more natural than lower priced kits. You’ll be more likely to find a channel in a given location that is not picking up interference. It is easier to hide and mount on talent. It is rugged and field-tested. I would also consider a mixer from sound devices.

You can get very good pictures from decent consumer level cameras if you give them enough light or just shoot in good light. But working with cheap audio gear creates an end product that is just annoying to listen too.
And one more thing: monitor with a good set of monitoring headphones.

No question audio requires some skill that comes with experience. But with a good mixer you can watch the meters and with good headphones you can hear what is being recorded and with a good mike you stand a chance of recording something your audience will enjoy.
I think you should consider investing as much in your audio gear as you do in your visual.
