Need help choosing reciever/amplifier

I moved to an new appartment some time ago and I need to set up my home "entertainment system" and I could use some advice. I bought a gramophone (this one) and it requieres another box (here) to simply connect it to an output or, and this is where I need some help, a reciever which provides the same service as part of the package. So, I am looking for a box which would unify all of my equipment, meaning the record player and 4 HDMI ports from my consoles and PC and output that to my reproductors (2.1 stereo at the moment) and TV. I have no idea where to begin, as you can see by the chioce of record player money is a concern so I would lean towards the cheaper solution if there is one. Thanks!
