Sigh. What do you expect, guy?
There are dozens and dozens of reputable ham and wire dealers. There is no "One Right Answer". If there was, we would all buy there and the other dealers would be out of business.
"Cheap" and "Suitable for your use" can only be determined in your mind. You've already obviously rejected several perfectly good suggestions.

You gotta do your own homework. We can't read your mind.
Even with the high price of copper these days, the price of coax, for example is far cheaper than it was 20 years ago, and the quality and selection much better. I can't compare copper wire as it lasts so long that price is really never a factor for me. However quality is.
Good luck on your quest. b.
