Well done, Hughes/Schweizer 300 is a good choice.
A really nice 'personal' headset can make a big difference to comfort, convenience and R/T quality, and the best N/R models are superb.
I'm a fan of Bose, but expensive new. S/h will be cheaper, but buy carefully, some may have had a hard life and they can get damaged easily if neglected, which could be costly to repair.
