Help with ANR Headphones

Hello everyone.

I have been flying with a regular headphone (passive noise reduction)
and have been considering buying an ANR headphone as soon as I get my
private license.

I would like to ask what types of tips people who have used them have
and also whether I will really have to spend $500+ for a headset. I
know the Bose costs $995 and that is out of my range. I saw a GCA (Gulf
Coast Avionics) ANR for about $250. Has anyone tried these? Are they
good or will I be better off with some other one?

Any suggestions will be appreciated.

Thanks,
Alex Vasconcelos
