Question About DWC Setup

I got my refund and I am really thinking about taking the plunge and making some bubble buckets, but I am really nervous about spending that kind of money. I am completly new to hydro and I just want to know. Is it as easy as everyone makes it out to be. I went to HTG and made a list of what I will need to buy. Can you all take a look and see if I am buying the right stuff to get started? Any advice is really appreciated.

I am getting the light no matter what, but is it really that much better/faster to go with hydro for the price????

This is the list I compiled...
Item Quantity Unit Price Total Price remove TEN PACK - 6" Net Pots
$12.50 $12.50 remove Rockwool / Stonewool 1" Cubes - 45 pack
$8.50 $8.50 remove Sunleaves TDS Essential Digital Test Pen

$15.95 $15.95 Subtotal: $278.06 Shipping: $51.70 Tax: $0.00 Total: $329.76
Do the prices look about right to you all???
