I bought two simple rigid heddle looms secondhand online. Identical ones, that was imperative. For a future project. Not ready for this project yet, but I could not resist this offer. Now I can go and try working with two heddles on one loom.
Did not know it when I sealed the deal. But when I opened the box, I saw they are of a quality brand. The seller could have asked way more than she sold them for.
Looms are one of those things that seem to show up in waves at the flea market, for the longest time you'll see none then you get one to sell and every other person there seems to have one 
Do you dye your own fabric?
At the moment they are everywhere indeed. Most of them have a wacky and horrid heddle mechanism. I had one of those as a kid, and utterly hated it, because it would never do what I wanted it to do.
Online most of the simple looms offered are those. And some expect big money for it too.
My brother told me last year I'd be having a loom within a year, and I said I did not see that happening.
I've a beginning weaver. But I like to play with the technique, without going to a big loom. Don't have the space nor the money for playing with stuff like that.
I have dyed some of my homespun wool. And my last project was a cat rug, with a weft of my own wool. Taught myself some new techniques that way.
Cat loves it, and it turned out well enough for me too. Second thing I made sofar.
It is funny to see how there are trends in secondhand stuff. Few years ago, everyone wanted porcelain enamel objects. Now that fad is over, and people who have liked that for decades can buy it again at decent rates. After that the whitewashed rubbish, and some whitewashed quality stuff was the rage. Seems to be fading now.
And, there is the hipster induced need for homemade stuff still going on. With a few years most looms will end up on attics again, waiting for the next weaving trend. Will make it more affordable again for the tinkerers at heart.
Know someone stocking up on small silver items at the moment. They are dead cheap, because not in fashion right now. He waits for the time that changes.
Somewhere in the eighties, if you inherited a big Frisian clock, you'd have to make your house more burglar safe. They were worth a fortune. Their value decimated over the years.
Intriguing stuff, second hand market.
