Gents,
Like the title says.  Console only is fine.  AV Cable and controller would be nice but not necessary.  Prefer a CGII, but a PC Engine will get the J-O-B done.  
Would like to pay around $60 for a CGII or $45 for a PC engine.  And i would pay a little more for cables or a controller.  Let me know if we can work something out.
