This should be in pre-purchase appraisals.
Also, for reseller, this type of domain goes for regfee.... enduser could be anywhere from mid $xx to low $xxx, but much more likely to be on the low end. I sell a lot of dot infos... you really want 1 word or 2 strong words that work together. Dot infos that have "about" or "info" or similar types of helper words tend to be very difficult to sell.
Hope this helps!
