I just bought a tow vehicle

and am now preparing to order a trailer. The tow vehicle is pre-wired at the dash for electric trailer brakes. It has a plug and an uninstalled mate to the plug with the wiring to attach to a brake controller. The plug in the back is a standard 7-pin connector and the trailer will have brakes on one axle. Total weight of trailer and car will be around 3000 lbs.

What type of brake controller should I be looking at? Is there a brand that people have used that they like? Any "gotcha's" that I need to be aware of? I am completely new to trailering, so any advice is appreciated. Thanks!
