DIY is also an option. They sell everything you need at Lowes/Home Depot or Amazon. Floraflex is a good system though.
Nice thing about drip irrigation is you can use it for soil, coco, or any DTW setup. I could switch to any of those, and would only have to change the grow medium.
I use a 30 gallon rez and it allowed me to go on vacation for nearly 2 weeks while everything was left on auto-pilot. First time ever doing that, so it was a little nerve wracking, but worked out perfectly for me.
I use short-interval timers that allow you to program hours, minutes, or seconds ON/OFF. These are a godsend, and allow me to schedule watering/feed however I want.
