looking into gear and with bcd i understand theres three types. not sure what one is recommended for a beginner . . . is something like this recommended for a beginner such as myself?
Dolphin Tech By IST Single Tank BCD w/ Deluxe Harness, SS Plate.
As TS&M noted, you can use virtually any type of BCD (jacket, back-inflate, BP/W) as a new diver, as long as it fits YOU. While it is always a sound recommendation to try out different systems before buying, that may not always be feasible, and it may be necessary to 'take the plunge' without a test drive / dive. There is something exhilirating about diving with your first new, personally-owned, piece of gear. While the first purchase is seldom 'perfect', the imperfections are frequently overshadowed, at least at first, by the joy of using your own gear.
With regard to the system you asked about, based on what is in the link: it is a back-inflate / plate system, has reasonable lift (30 lb) for a single tank, has a donut / 360 air cell, appears to be reasonably streamlined, and seems to be adjustable since 'one size fits all'. What I would not personally care for: the 'deluxe' harness is unnecessary, I don't like D-rings sewn into fixed positions on the harness (which appears to be the case with this unit), it probably has more padding than is necessary (and for which you will have to wear extra lead to compensate) and it is not particularly inexpensive at ~$600 (although it is probably less expensive than some other, new systems, such as the Halcyon). Having said the latter, all as a matter of personal preference, I suspect you would be quite happy with this unit, and I would not necessarily discourage you.
Ordinarlly, I would encourage a more 'local' approach to purchasing gear as a newbie, simply because of the hassle of dealing with a remote vendor if anything is not right when you get it, or there are follow-up warranty issues. If, however, you are planning to deal with a remote vendor (like IST, in Las Vegas NV) anyway, I would echo irishsquid's suggestion to at least consider Deep Sea Supply. First, you get A LOT of support before buying, and the after sale service is very good. Tobin (cool_hardware52) has been a big help to a lot of people on SB, is very knowledgeable, and easy to do business with. A PM to him might serve you very well.
There are also some other respected SB members in the US, like Jim Lapenta, who are now carrying a line of equipment, and contacts with them may be useful as well.
