Hey, taxman. There are a number of good choices, and the "best" one depends on your preferences, your budget, and which specific features you want.
Do you have a budget for this? There are some great receivers in the $350-$500 range. Some that come to mind are the Yamaha RX-V663, Onkyo TX-SR606, and the Pioneer VSX-1018AH.
If you do a search on this forum for those units (or even PS3), you will come across a few threads that specifically address features of these receivers.
