The original remote has the best mapping of button names to functions. However, there are a number of cheap universal remotes which can control the SR4200.

Marantz publishes the complete details of their IR signals. Given that data, we can see that any remote made by Universal Electronics that carries setup code Audio 1189 or 1289 is capable of sending every IR signal that the SR4200 understands. This includes just about any Radio Shack remote starting with the number 15-xxxx, any cable remote of the Atlas type, nearly any OneForAll, and higher end Vizio TV remotes.

Newer remotes include the OneForAll URC-8820/10820, and the RCAP05B.

The RCAP05B is easily available at BestBuy for $20; the OneForAlls are avaibable on-line.

If any button isn't mapped the way you want or you'd like access to discrete button codes like discrete power On or particular inputs, we can tell you how to program those codes individually to buttons.
