Just coming through as sold on Sedo is the domain imigration.com for $35,000. The name is obviously one "m" away from immigration. So it looks like a strong i keyword sale. The domain was regged in 1998. Whois shows Moniker privacy, looked to have been just a parked page.
SubscriptionEconomy.com is another nice sale today for $9500. The domain was registered last year. The domain was purchased by Zuora a company that calls itself, "THE LEADER IN SUBSCRIPTION BILLING & PAYMENT SOLUTIONS"
