They are all good. My son got certified by BWD. They are a very good company. They have locations at Nanny Cay and Soper's Hole. d_fish, a single diver will definitely be with a group unless she wants a private dive $$$. She will have more fun with 4-5 other divers. Kim do you class room and pool work at home and then you will only have 4 dives to get certified in BVI. You will do 2 dives one and and 2 dives the next day. Then you can get a scuba tank so you can clean your boat's bottom, work on the prop, clean out through hulls, so much fun <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" /> seriously, you will love it.
