No, I mean that there are as many Rio remotes as there are Rio Car units. Actually, if you count the spares that are probably in the hands of the Rio guys and Rob S., there are probably more Rio Remotes than Rio Cars.
I don't know how many empeg bags there are, but I'm guessing the number is fewer than the number of empeg Car units, which in itself is significantly fewer than the number of Rio Car units.
So, in relative terms, the bags are extremely rare, whereas the remotes aren't much more rare than the players themselves.
