Default General purpose 20W+ amp

I am looking for a general purpose D class amp that I am going to use for some of my experiments. I do not want to invest much and I do not expect to get any good audio quality. My requirements are:
- Available on eBay
- <=$20
- >=20W
- Stereo/Mono
- 4-8 Ohm
- 12-24Vdc

At the moment I am considering TPA3116, TPA3100D2, TPA3118D2 and TDA7492P. Could anyone please recommend which one to pick?

TPA3116 would be my choice. If you didn't know: if you want to use it mono you have to parallel the outputs, not bridge them.
