What are you doing that needs so much gain? Sometimes the other details are critical. Is noise or impedance an issue?
6MHz flat gain is a standard video amp chip. To get gain of 900, try two chips with gain of 30 (30*30=900). Two of µA733 (a chip that is probably older than many people here) will do gain of 1,000 out to 50MHz, if you can keep the output from feeding back into the input and oscillating.
