Best version/alternative to Spare tire rims?

I'm looking to eventually throw some black steel rims onto my 05' RCLB, but have been discovering a variety of options. Per usual, I figure y'all are the people to talk to. I have a white truck and white aluminum camper, so I need some black and don't want anything too flashy.

My main option so far is picking up a set of new spare tire rims for about $80 each. What I'm mainly considering about this is scavenging together a set of used ones, or any sort of hubcap to spruce up the look. Is anyone familiar with a good place/ way to pick them up or find hubs that would fit?

The high end option would likely be something like this, or a cool set of 2nd hand chrome one's off an older pick up. This would really add up, and I doubt I need to throw fancy rims on my truck that gets mistaken for the repair man's car. Rather, I like keeping it subtle as I like to travel to mexico and urban camp often, though these ones aren't too flashy.

What do you guys think? I've seen a lot of people here rocking bare spare rims, and I'll likely be joining unless I find a suitable alternative.

Thanks
