I got an Eomer off ebay a couple of months back. Maybe it is the one you remember. I got it for about $40-50, I am not sure anymore. And I like the Eomer as a cheap back-up to bring in late in the game. Worked pretty well on a couple of occasions.
I would love to get the Arwen, Frodo and Boromir. Stormcrow and Gimli do not appear to have much play value anyways...
