First off, welcome to the board! We hope you have enjoyed what you have discovered so far and we look forward to your contributions and questions.
Second, we need more data about you in order for us to recommend the type of exposure protection so suit your needs. Where in the country are you diving? What sorts of dives? Are you usually a warm blooded person or do you get cold easily?
For my coulder water dives, I've got an Xcel 5/4/3 wetsuit that I am very very happy with. Lots of great features, easy to get on and off, and most importantly, I can hit the colder waters (upper 50's and low 60's) and stay there for a while without getting chilled. It was a bit on the upper price side ($250) but for the quality, I consider it a good purchase. There are many other brands that are good such as Henderson, Parkway, O'Niel and many others. I'm sure there are those here what will be happy to share their experiences.
On the computers, Suunto is a good choice and many of the regulars hear use their system. Several folks use and like the Cobras, as well as the Vypers, and the Mosquitos.
Myself, I use the Genesis ReACT and find that it is a good computer, and conservative to my liking (I usually run out of NDL before my buddy with his Aladin). And if I do flip into deco, the info shown helps me get out of trouble with no problems.
I like you look forward to the other folks answers. So let's hear them, y'all!
