does anyone know of such a setup, or a low price place in the united states

Also consider the possibilites in the "amateur radio" world (commonly reffered to as "Ham Radio" especially in the USA).
Various clubs and associations will from time to time organise "junk sales" or "Hamfests".
Here one will find all sorts of stuff, new, old, good stuff, junk, overpriced junk, a gem of a bargain.
Unfortunately I cannot advise where to find one near to you in the USA.
I do know that there is a BIG one which takes place every year in Dayton Ohio, this years event took place a few weeks ago.
I am currently in Friedrichshafen in southern Germany, attending the biggest such event in Europe.
There is all sorts of stuff there from small components for 1Euro a bag, to test equipment costing 10,000 to 15,000Euro.
And a good time was had by all!
See here, for information:
For the Dayton event, look here:

There are also many smaller local events rather than having to travel hundreds or thousands of miles.
