There are a lot of hitches out there. My first piece of advice is to get one with built in sway control. I am not a fan of the add on friction bars. Call me lazy but I don't like the idea of hooking up this extra piece of equipment, tightening it to some magical level and then having to remove it when backing into tight spots.
I am no expert but I am happy with my Equalizer. Mine does not make noise. I have it dialed in and use lubrication at the points the manufacturer recommends. Again, there are lots of good ones out there but you will have to take into consideration your tow vehicle and the weight and length of your trailer. Saving money is always a good thing but going "cheap" is never a wise decision.
