A lot appears in NG alt.radio.digital on these.
I got mine from PC World, part of Dixons.
I and many people have problems with them and our computers, so a lot get returned to the shops. So I would keep trying branches of these shops around your area, or even press them to look on thier computer to see which branches have one. If you do find one, open box there and check CD and power supply are in the box along with Wavefinder and rods.
