I've had good results with using a redundant wireless modem/router as a WAP. I've actually placed it quite some distance from the primary router/modem using cat 5 cable to get the 'WAP' in the best location for devices which will work with it.
I'm also a radio ham, so the introduction of any devices which radiate even more crud into the spectrum is resisted with considerable vigour. There are already far too many such 'appliances' and gadgets which do significant damage to the receiving side of the hobby.
