Are there any 30$ ish amplifier modules for up to 500kHz?

I am thinking of using it with a functiongenerator.
I would be happy with 2W, and +- 5V.

Thanks for those links.
The first item is denied by ali express in my country!  :rant:

The juntek has 2x gain? Can it be disabled without compromising the performance?
