x 2 on the TC stainless inlines. TC really knows how to dumb things down and keep it very simple. Few parts, great warranty, and you can find a good used one for 100 and change, so you can buy it and keep it 'just in case' without feeling bad if it ends up sitting for a few years.
Other items? There's not much more you NEED, but it's all the little gadgets you will WANT- kinda like fishing or archery- ton's of extras out there. I think most places have starter kits with the basics for $30 or so.
