Is there a source for just RF receivers?

Projects General Guidance

I see lots of places to purchase pairs of RF transmitters and receiver boards - however. My task will be to have one transmitter broadcasting - and multiple receivers listening. There would be no handshaking between them.

Seems like a waste to buy 10 sets, and 9 transmitters left over - which wouldn't be wasted - I'm sure I'll find
uses for them for other projects - but just curious if there is a source of just receivers, and of course cheaper than
the set, otherwise I'll just start building a collection of transmitters!

Are these any good?

I would say: both are bad.
Those are the receivers that I had been using. They tune the frequency with a coil. I don't buy those anymore, but only receivers that use a crystal. They cost 1 or 2 dollars more on Ebay.
