They don't make them anymore, so you'd have to buy a used one. Sony was the last one to make one, with a blu-ray unit (also played DVDs.) Pioneer, Kenwood, and Onkyo also had at least one model apiece (probably all were Pioneer built.) You can find the Sonys on eBay or Amazon quite easily, but the others are harder to find.
None had RF capability on their own, but you can buy an RF remote and RF/IR repeaters for that.
Don't believe everything on the Interwebz! A duck's quack DOES echo!
