Don't ever go by those automated estimates. They're always WAY off. I once bought a brand new, never registered, non-generalized domain and right away one of those estimates said it was worth $32,000. HAH!
If you can find someone, who uses Estibot to get a appraisal than It's a good idea to buy But I don't really trust estibot..
Yeah you just found a pretty good domain and good extension. You should just go ahead and purchased it before anyone else do. And i believe if you really work well with the link building then your domain will worth more than current value
thanks to all the good think is overture/month and wordtracker/day but I dont like google results anyway I gonna buy it
