I bought a headset from
http://www.flighthelmets.com.au/products.htm going on 5 years now and no complaints what so ever!
When I bought it it came with gel ear seals which were (at the time) reserved for the more expensive headsets.
The weight is reasonable, it is very comfortable, doesn't feel flimsey and the flexible mic boom is much better than the hinged set up some of the cheaper headsets out there have.
