Have decided to go with an online screening site auto pay , the whole smear.. Would like to hear from those who have used different places, PLEASE include who  they are , what you liked or did not like about them,. would you use them again. customer service issues, cost,  turn around time,   and any thing else you want to throw into the mix.  Especially want to know about rip off sites to avoid at all cost! Thanks
