Ok Andree, I'll try to tackle this one.
High $1,500
Low $500
Based on the following analysis.
Upper limit sales are likely to be:
$12k based on ComputerSystem.com sold at Moniker April 2007; and
$2.1k based on HomeTheaterSystem.com from BuyDomains Dec 2006.
Keyword Discovery and Overture show the following search strength (higher is better):
Home Theater System - 12,386, Overture 108,949
Computer System - 3,543, Overture 45,746
Multimedia System - 69, Overture 987
Meaning we expect Multimedia System to be lower than the other two.
Giving the benefit of the doubt, let's exclude HomeTheaterSystem.com as someone getting a good deal.
Let's also say the percentage popularity of Multimedia to Computer System is 987/45746 or about 2%. 2% of the $12k for computer system gives us about $250. Make it $500 since that just seems a bit too low from a seat of the pants glance.
On the other hand, in Google search results, MultiMedia is about half as popular as Home Theater System. So, let's set an upper end of $1.5 k based on half the sale of Home Theater System plus a little appreciation in the last year since the sale.
