I'll jump on the DPM bandwagon. I finished my OW cert with them in February, and can say they are a great shop. Friendly, laid back people with nearly brand new equipment, a great patio for beers after the dive, and 15 minutes from 2 great dive sites.
I dove My Reef 5 times and saw different stuff each time from crabs and lobster, to schools of fish, to a healthy reef, to barracuda and an moary eels. We also dove the C-56 which is old U.S. minesweeper sold to the Mexican Navy and sunk as an artificial reef. Its got access for easy, safe swim throughs. We also saw some great fish there including a monster barracuda in the wheelhouse, some stingrays on the ocean floor and a school of cuda as we descended.
Best of all, my first days dives had 5 people including the DM, the second day was one on one with the DM and the final day had 5 of us diving again. No cattleboats. Take a dive with Cat, Kris, 'Yip, and Brett and you'll love it. Final positive, dove the C-56 at 85 ft with no websuit in Feb and didn't get chilled a bit.
Enjoy
