it looks like it is getting little traffic (100+ hits a month), unfortunately my guess would be that since most of the traffic is european the conversion at Sedo is pretty bad, I have a couple of domains in that field and its really not that great, the traffic is ovbiously nowhere near the .com (which might be the only reason you regged this)... I would guess that you maybe make a little less than $2 a month on this in parking , so a fair value might be around $60..
