Given that the rig looks very small, was very cheap and having heard a lot of bad stuff about the quality of sahara smoke narghiles i'd bet it was poor choice. Frankly, I don't think you can get a decent rig for $30. In my experience you'd have to spend at least $50 to get something worth having. It makes no sense trying to save money on a narghile as you'll easily spend a couple of hundred on shisha and coals within a year so you may as well get something that will give you many years of good service.
I'd recommend Syrians from Furat or J & R or a KM or MZ if you prefer Egyptians. I'd also suggest you stay away from Mya and other Chinese stuff.
