Good Earth Tours

Has anyone used Good Earth Tours for a Tanzania safari? Their prices seem great, but I am just wondering because they are owned by someone in Florida. I read in the lonely planet guide that it is a bad idea to use a company that is not local to Arusha for the Serengeti tours. I'd appreciate any comments/advice!

Hello!
The company is owned with family so there are one guy within the family who is leaving in florida working as an agent there.

They are good because they all born and grown up in Tanzania.
I dont think if its a bad idea using them as ndashi have been so good in the industry.
Happy new year and dont hestate to use them,
Regards,
