Hello Rodja, welcome to the forums. The Eros is a '90 which was the first year for that model and the only year it came with Suntour Radius. Starting in '91 it had RX100 w/ a triple. Depending on you your location I would say $250-300 is fair, in a hot market like LA maybe 300-350.
The Brava... More information would be helpful but I think the Brava is a 2002 model, I cheated and used Bikepedia, and as always it depends on your location but $350 to 400 sounds good to me.
