The Toy Fair Vader is a figure that seems to have really held its value over time. That last few I've seen on eBay still go for about $175US, give or take. I've just never been willing to spend that much on it, despite it being a very unique figure with the saber going through the bubble.
A friend of mine offered me one for $170CDN, about $140US, which is very fair with today's value (and considering he paid $200CDN for it). But I just couldn't convince myself to spend that much - one moment I regret it, the next I'm glad I didn't spend the money.
Any others still needing this?
