"Old Days"premium names like this are nearly impossible to casually 'appraise'. Whenever one pops up on the appraisal forum, people tend to go a bit bonkers with their appraisals. The best you can do is throw your line out there and see what bites. Be patient. A large portion of it's sale price will be determined by how fast you want to sell it. This name is absolutely a candidate for a premium, real world live auction.
Yeah, text.com is ideal, but this is still a very valuable name. Matter of fact, given the progression of technology over the years ie text messaging, this name has a much higher relative value today than it would've some years ago (note- relative value. Obviously, given how premium domains have risen in value over the years, any good name is worth more today :D)
