Any of the below will have discrete's...ortho I have not had much to do with Onkyo low end Receivers.
Onkyo TX-SR308 $299
Pioneer VSK-520-K $229
Pioneer VSK-820-K $299 (My pick)
Pioneer does not have the IR codes for these models on their site yet but the
VSX-519V IR & Hex Codes will work.
You could also go with Yamaha or Denon but they cost a little more.
Check the depth of your cabinet and allow for cables/connections.Cheers
