Have not been to a Hamfest in years, but I think that is one of the best places to look for an “inexpensive” Ham rig.

Or even better, find a local Ham Club that has license classes. They are usually the people who give the exams.
I first sat before an FCC examiner in 1976, on Commerce Street in downtown Dallas. Had an Advanced License from that year to 1985 when I took my Amateur Extra exam. Commercial license came later.
Amateur Radio Clubs vary a lot. Some have a lot of technical oriented members, others don’t. There was a time when most were X-military or worked in commercial radio fields. Not so much now.
Now they give you the question pool and the answers. It makes it a lot easier to prep for the exam.
When I got my first license, there were study guides but the question pool was blind. I was scared to death for the first exam.
I’ve taught both Amateur and Commercial Radio license classes. (not recently)
Over the years I have been fortunate to meet some of the most interesting people because of Amateur Radio.
If you’re asking about antennas, I’d say Kent Electronics. http://www.wa5vjb.com/
