My house is in one of those spots that does not get any good cell reception. We have had an antenna for a few years, but it has only marginally helped. I decided to get the VZ Network Extender and am extremely pleased. It does not have EVDO capability, but with WIFI on the Droid, I could care less. What is has done is give me 4-5 bars in every spot in my house. Basically I went from an average dBm of -104 (0 t o1 bar) to an average of -79 (4-5 bars and much much better).
It is by no means cheap, but well worth it if your house is in an area like mine.
