FWIW, I bought the same regset for my son. It works great. I paid a lot less though. At $425 (the unbundled price), I would go with the Deep 6 Excursion X series instead. The second stages are better, DIY servicing will be way less of a hassle, and it's $25 cheaper until their Black Friday pricing ends.
Other that that...
At $150, I think the Puck Pro+ is the best deal right now for a basic nitrox computer. You would need to jump up almost $400 to get something appreciably better. When you do decide to upgrade, you've got a cheap backup or you can probably sell it for $100.
BCD - Less is more on BCDs. If you are determined to get a standard BCD, then the one you selected is fine and it's cheap enough that you won't feel too bad when you upgrade to a BP/W
Intro to Backplates and Wings
This thread is to help beginners or those interested in backplates and wings (BP/W) understand the concept and design features. I will try to cover the majority of your questions in this guide. However, this guide is not fully inclusive and it is written to provide an entry level knowledge of their design and function.
There are four main components of a BP/W. They are the Plate, the Harness, the Wing, the Tank Attachment (STA or Bands). Below we will discuss each in detail. The BP/W is designed to be a modular unit. This means in most cases you...
Wetsuits. It's nice to be able to try them on, but if you are a fairly normal size, a modern stretchy wetsuit in your size will usually work well. Also scuba.com is very good with allowing exchanges if you need to change sizes.
Mask - buy local unless you are really cash strapped. If you do go mail order, make sure you can exchange it. One hint that could save you some money at the local shop is that fit is by far the most important factor. The cheapest mask on the shelf that fits you is fine, there is little to no advantage to higher prices masks. Other than fit, low volume is better than high volume assuming your nose fits. And a dark skirt is better than clear skirts.
