Recomendations/opinions......
Yup, you'll find them here. Everyone seems partial to specific brands. If you do a search on the items your looking for you will find some very good info. From what I have read, most on this board like Suunto computers, ScubaPro & Apeks regs, and assorted BC's.
IMHO, the best thing is to do some homework. Read the posts here, read from other sources, go to the various dive shops around and try out some stuff and ask questions. I try to buy brands my LDS can service. Only you know what your needs are and what's comfortable for you.
I am looking at purchasing a new reg myself (I hear there's a new one coming out from Atomic) and I'll be trying out as many as I can. Santa was good to me and I got a new computer (not a Suunto!) which I have been researching for a while. I think it's hard to find bad equipment although I'm sure exists.
Just my .02 and there's plenty more to come.
