RUAG owns the GECO brand, as well as RWS (and Rottweil and Norma). GECO is what you might call the economy line to RWS. From what I was told by their former agent here, it is exactly the same brass, just without the final polishing given to the RWS product. It is also loaded with more conventional bullets.
FWIW I have had excellent results from some GECO brass in 9.3x74R.
