No one makes them anymore (and none had an RF remote, ever.)
Sony, Pioneer, Onkyo, and Kenwood made them. Onkyo and Kenwood's were likely rebadges of the Pioneer, which held 300 discs. Sony was the last one to build one and the only one with upscaling. It held 400 discs. The others would be several years old at this point and finding a decent one would be tough.
eBay is your best bet. Amazon might have a few, too.
Sony's BDP-CX960 was the last one built, and does DVD and blu-ray. You MIGHT even find a new in box or open box one. The older one is the DVPCX995. DVD only. A new one of those would be a miracle.
Don't believe everything on the Interwebz! A duck's quack DOES echo!
