Ed Brown second hand market tends to be softer than other 1911 semi custom shops, but you never know what something is worth to the right person. I'd be tempted if I saw it in the classifieds, but two tone with target sights is my favorite configuration.
You'll get better feedback from the 1911 section here, or even better a dedicated 1911 forum like 1911 Addicts.
Great looking specimen you have there!
