Was going to setup a pot blaster to clean some headers up. Was looking at my options of media? Tractor Supply sells glass and garnet. Is there other options at a reasonable price?

Soft or fine sand. Hard or coarse sand is for stripping hard coatings and paint. Can probably buy it as mortar sand.
This has been discussed 100 of times ...........
Yes ........safety is for sissies:

Are there sands that do not contain crystalline silica?

For headers, a fine media will leave a smoother surface.
Get an aggressive 'sharp' media which will cut thru the rust. A 'smoother' media like glass beads won't cut as well.
TSC also sells Black Diamond coal slag. I haven't used it, but it gets good reports.
If I'm blasting outside, I just use sand and wear a supplied-air respirator. It cuts well and can be reused a few times before turning into dust.
For a blasting cabinet, I like aluminum oxide. It cuts well and lasts longer.

Menards sell the black grit. Cheap and worth a try. It's usually by the sacks of concrete mix.
On the safety and comfort side again...........respirator or filter or outside is NOT enough. Bare minimum get a blasting hood and coveralls and hose them off outside.
If you ever blasted you know the grit gets everywhere. All your clothing and everything gets covered in grit and dust. When you taste dust or grit in your teeth , eyes watering and at night your burn.....you feel like you were in sand storm .........you know dust has made it through. Blow your nose that brown snot **** might be a concern.

A dust mask is not sufficient. I use a simple paint respirator and a face shield and work outside and if there is wind stand upwind if I can, also do stick my face right in it. Blasting a set of headers is different than working with a career in blasting.
I have used supplied air, some places there is no choice.
With some caution a few minutes it takes for headers can be coped with.
