So, I've been persuaded to look at the Quadrafire Isle Royale in my dealer's showroom as opposed to the Hearthstone Heritage or Mansfield we were going to buy. It's the 2009 model, brown, only lit once and getting it for $2799. Does anyone know if the specs are the same for 2009 and 2011? Have there been good changes that would convince me to leave this deal? Thanks!
