Yeah, dwc is super simple and a great place to start with hydro, IMO.
Personally, I started out in soil, and after I harvested my first run I set up a simple aeroponics system-- it was really easy to design and build, and I set up a 4 site for less than $40 including the fountain pump. I could've made a 6 site or whatever; I could've made it big enough to fit 15 plants honestly, (if I had the light) by buying one more 10' square tube.
Its just a simple res, with a square tube that sits on it coming in from the side. A fountain pump sits in the res, and pumps the water up a line, and the line runs down the inside of the square tube. Just poke holes wherever you want your sites. As long as you keep the far end of the tube higher than the res end, the water drains back down to the res where it will eventually get pumped back up again.
I was in the same dilemma as you, I wanted to try out hydro but wasn't sure which route to go. I figured I would start out with dwc, but then I saw a $300 aero setup and I thought "shit, that would be easy to make".
I highly recommend tho, that whatever you go with, you choose some type of recirculating system. It was a tip I was given by a caretaker in Colorado, and quite frankly I think it was good advice.
