TRIO AG-203 CR OSCILLATOR – This was bought in 1999, in a store in Santa Ifigênia. I paid R$15 for it, a real bargain!! Something around USD18 nowadays... I bought it with a CO-1303D that I gave to a friend some years later. I only did electrostatic painting in the AG-203 and the CO-1303D and the rigs were ready to work. It is a very cute unit and its operation is very stable. I use it most of the time for square wave jobs. The LAG-66 is better for sinusoidal. The only problem this models have is the range switch that sometimes let you nuts... Use good contact cleaners and it is OK.
