Don't buy anything cheap .
A. If you decide not to keep flying something like a DC will be much easier to sell and will fetch a better second hand price.
B. If you continue flying you will be pleased you spent the extra money.
I've had a DC 10-80 for well over 25 years and over 7000 hours of flying. It's never let me down.
I've had many sets of cheaper headsets given to me to repair. Many, even though they they looked similar to a DC at first glance, were just junk.
If you're not sure whether or not flying is for you buy a second hand DC or similar if the new price is outside your budget.
