Most of them I've run into over time seem to fall in the $50-$70 range. Darth Revan slightly less, but still egregiously expensive for what and who he is.
Expanded Universe figures always command a hefty price. Go take a look at current eBay numbers for Jacen and Jaina Solo or Bastila Shan. It's highway robbery conducted by toy geeks.
I actually have a spare carded Bastila Shan. I hate scalpers but when you look at the prices commanded by these figures I'd be lying if I said I wasn't tempted to stick it on eBay.
