Glad to hear you have narrowed it down. If you have the opportunity try to rent or borrow a water system. I made the mistake of buying too much gear too quickly. I ended up with little money and a bunch of heavy gear(i.e. miniworks ex. great filter, way way to heavy!). So if you can use some gear before buying, do it. See what works for you. My .02. Good luck!

PS. dont forget a backup!
