esti is generous, i got it at mid xx. Only stand out use is that 09 was his inaugural year. Many of those searches i believe are looking up his 09 tax returns
Good example of a time-sensitive domain
Personally I think only 2008 would have made sense (still obsolete though). We are in 2010 now.
Possibly 2012 can be worth something too but it will be obsolete at some point not too far in the future. Even regfee is generous, because I'm not sure you can sell it for $8. Good luck.
Heck if esitbot says it's worth that, just half is still a nice roi!! I'd renew it for a few more years, and see if you can get someone willing to buy it.
