We took a tour with Cosol in April of 2006 and loved it! (Actually, we rode with his brother Yellow Bird who is also great – he drove behind Cosol in a second van and we had it all to ourselves.) It was the highlight of the whole trip.
He hit all highlights of the island: The botanical gardens, the Pitons, the "drive in Volcano" and other scenic highlights.
Make sure you taste all the treats he supplies (no additional charge) on the tour. He stops at various places along the way to gather goodies. The local bread he buys is different from anything I've tasted and I wish I had the recipe. Also, don’t miss the fried fish with banana ketchup that he will offer you at the botanical gardens. (not to mention his delicious rum punch and Piton beer)
This is the e-mail I used to contact him last year. I hope it is still good.

There is another well known guide known as "Frank's Taxi" We did not use him but heard he was very good as well
