Hm... A jacket from XS Scuba costs about $380 (I didn't do a lot of shopping) and a DSS BP/W costs about $524 (large SS plate with Pro-Fit Harness and LCD 30 wing). The wings alone (no plate/harness) are expensive - usually in the $300+ price range.
Tobin's gear at DSS is excellent gear. But if we are talking cost wars, you can get a complete Golem Gear rig on sale right now the next few days for $370, so the $10 advantage goes to bp/w.
Golem Gear, Inc.
There are enough deals out there for jackets as well as back plate and wing combo's that price really should not be the deciding factor.
I have been diving a Golem rig for a couple of years. I learned to dive in Scuba Pro gear. All things considered and a couple of years down the road, I am very happy with my gear and I would buy it again.
The most important in thing in gettin gear is deciding what is important to you. Some folks like to stay with they type the learned to dive with--and there is nothing wrong with that. Some have other considerations and that is fine to consider too. For me, the jacket gear always felt sloppy and rubbed some nasty spots on me when I dove without a wet suit. I found the shifting to be most uncomfortable. I also did not like how it felt when I inflated it. So I began to look for gear that removed those problems for me. I am also working on dropping a few pounds and I didn't want to have to keep buying gear as my size changed in any direction. I have a few curves and wanted something that would work well with my shape.
So after much research and talking with many owners various types of gear, many satified and others not so much, I decided that I wanted a bp/w. For me that has turned out to be a good choice. After that I spent a lot of time looking at price and quality. Both were important to me. I priced out the system a ton of ways from a ton of places. In the end Jakub at Golem got my business. It sometimes takes him a few days to get back with you, but the price and quality were well worth it. He has been great to work with.
There are many places you could purchase a bp/w for an excellent price this time of year. Golem, DSS, Scuba Toys, and Dive Sports. All are members of the board and all provide excellent products and customer service. I have had dealings with all of them and could recommend any of them in good faith. The first two the companies that make the gear and the second two are retail shops that carry many lines of gear.
And here is my deal or connection to the above 4 companies. When I joined the board, other satisfied customers told me about these dealers and how good they are. I called on my own, got great service, prices, and products. So now I tell others. As long as I know they are still running a top notch op, I keep spreading the good word as a favor since others were kind enough to share the info with me. As soon as they slip, I promise to bad mouth the accordingly and warn others to stay clear. So far years after dealing with all of them, they continue to do a good job.
Anyway, back to my thought. Decide what things about the gear are important to you and then find gear that will meet those needs or desires. Each of us have a little bit different set of wants and needs. There are enough choices out there so once you decide what you want, there is a product waiting to meet that need.
