I've been using the Ramsey Electronics 1 watt FM transmitter (FM35BWT) for about 5 years continuously in my my house. Although it goes up to a watt, I only output about 1/2 a watt.
I also have used the C.Crane FM transmitters (Item # FMT) that have the easy mod to boost the output. This should cover a normal stick construction house. (I had to get the Ramsey transmitter when I moved into big concrete and rebar homes overseas).
There are also lots of options on eBay but I had trouble getting the antenna impedance to match up correctly on the one I bought.
