Seeking input from pickup truck owners who bought a headache rack, ideally in NW Houston.

Thinking about a rack from my pickup truck. I see 'em on Amazon. Got my generator on Amazon and that was easy.

Would rather go to a brick-and-mortar and see some options, but don't want to get swindled.

If you got a headache rack for a truck somewhere in the NW part of town, I'd love to hear how it went.

Edit/Update: I'm not strictly looking for something to protect my rear window. I want the rack to have a good overall appearance.
