Just make sure of one thing, whenever you look at a "Roku M1000" ad make sure
that connections are under the caps and not on back. There are currently at least
two "M1000" ads on ebay that are clearly M1001s.
Many Rokus have M1000 labels on front and M1001 labels on back, these are 5V M1001s
and they transcode and degrade signal so are less desirable.
