I have the Telex Echelon and it's just fine for a cheap starter headset.
I also got a spare headset off ebay brand new for £50. It's a Pregizer. I've tried it myself and it works a treat - dual volume controls and gold plates plugs - better spec than my Telex actually !!. - Just search for Aviation Headsets.
At my flying club, there were career instructors still using their first Telex Echelon from when they were a PPL, albeit held together with gaffer tape !!.
Save your money for the flying is my best advice. You can always upgrade at a later date and use your current h/seat as a spare then.
