I have seen Pico Origa SE on sale only once.Pico and ALO Continentals are both impossible to find.
As for the ALO CDM, it was much more frequent. I myself recently sold my spare device. Probably, this is due to the circulation and price. As far as I know, Pico has a much smaller circulation and a much higher price.
