Wifi vs. Powerline adapters?

[shellyesmalls]

Trying to find a good networking solution because I am in a long house and the cable/wired router is in the front and I am in the back and worried about range speed of Wifi. I am looking at these Powerline adapters:

Anyone use these or Powerline? How is Powerline speed?

Powerline seems cheaper then a good N router and for my house might be more stable, right?

These powerline adapters are homeplug certified, but the non homeplug certified are cheeper, but the homeplug ones seem faster what dose homeplug really mean?

HomePlug is a standard that ensures compatibility between products from competing manufacturers, I think (not that I've tried mix and match).

I use HomePlug AV devices around my house - lounge, bedroom, loft and garage - and they work really well.  Speeds are definitely faster than wifi.
