Have you read through the first link I posted above?
First of all what amount of money are you able to spent for the controller? Which hardware (mainboard, CPU, amount of RAM OR server brand/model) do you have?
Sometimes the above mentioned re-branded LSI controller are available for less money as used/refurbished but that greatly depends on where you are located.
So it's pretty hard to point you to one single model which might be not available for cheap or at all at your side.
Usually with ordering a server you have a limited choice of compatible controllers by the vendor and thus if you build the server yourself you have to do some searching/reading.
