Antywanty,
You're right--it ain't rock science. And the answer to fear is knowledge. I know that there are places out there like Hair Club that like to 'keep you in the dark.' They don't want you to know that there are different types of bases and different ventilations. They just want you to sign a contract and pay exorbitant amounts. You don't have to pay an arm and a leg to look good. Learn to do it yourself and you'll save time and a bundle of money.
Regards,
John
