I'm also newly certified, and went through the same thing. The suggestions of Deep Sea Supply or Dive Rite in scuba are good ones. Both will get you set up correctly. In my case I came across a solid LDS that had a nice line up of Hollis BP/W gear, so I paid up a bit extra (compared to DSS or DRIS) for local support.
If I hadn't found the local guys, I would have gone with Tobin at DSS. He is highly respected around here for his knowledge. His level of analysis and support is really helpful for a newbie.
