The nomad is a sidemount rig. Are you planning on going sidemount? What are you looking for specifically? What kind of diving do you plan to do? Do you have a specific mission goal that requires more than a basic back plate and wing with one piece HOG harness? Are you setting up doubles or plan to in the near future? How much money do you want to spend? What BC's have you used so far? Does your dive mission goal require you to spend $700 on a BC?
You have according to your profile less than 50 dives, why do you want a specialized sidemount BC? I hope you are evaluating your needs based on your training and experience and not on the "cool factor" often used by new and inexperienced divers.
Many times new divers get talked into or focused on how a piece of gear looks rather than how well it will function for them. Shops love this. This is how they are able to sucker people into paying through the nose for BC's with 20 d rings, big pockets that are pretty much useless, lots of unnecessary padding, integrated inflator/octo's, and other gimmicks. This is how they talk a new OW diver with more money than sense into buying $750-1000 regulators when a $250 one will do them just as well.
Take your time and really look at what you are doing. Evaluate your goals for 6 months from now, 1 year, 5 years. Realistically ask yourself what you need to accomplish those goals right now. And for God's sake don't get focused on one brand.
