I use Bluesmirfs as much as I can, very easy to use [and yes, the price shows it].
I get 450 feet of range with the Smirf RP-SMA from Sparkfun, an Amped high-gain panel antenna, and a basic android phone. Yes I know that's about 100x more than you're looking at, but it shows the potential. Get into xBee and you're talking MILES. (hint hint, I have an FCC license)
