I think the above appraisals are too high. Great name, but you can get a few two letters for high XX,XXX. I think there was a thread recently where there was a decent two letter with a minimum offer of 75K, which makes 75K a relavant number for a two letter...whether he sells it for that price or not. I know most two letters are XXX,XXX and higher though.
25K for me, but many of these names are becoming like prized paintings and very exclusive, so you could get lucky and make a bigger score. Time is on your side and we aren't quite at the mania phase for these types of names, so wait it out for a few years and you might get 100K.
