Do you **NEED** 10w? There are lots of DIY SET & PP amps that should work really well with single driver speakers, although mostly at lower power.
If you don't need all 10w, Check out Pete Millett's page for the Mighty midget for an example. Only ~3w, but it looks like it should be nice & easy to build.
I almost like the ~$500 Chinese speaker amps. They can sound pretty nice. My biggest complaint is that its difficult to know whether you are getting the version with all the nice parts, or one with a crappy power supply, or exactly what really. I'm also not really a fan of how absurdly tight the chassis are packed and consequently how hot they get.
