Bluetooth Handsfree Speakerphone

[gyroslice]

i am having a difficult time finding a usable Bluetooth handsfree speakerphone to use in the car with my Fascinate (Verizon Stock ROM). I've tried the Plantronics K100 (dropped calls left and right), the Blueant S4 (hard to hear on my end) and the Parrot Minikit slim (callers all complained about having a bad connection). As anyone had any luck with Bluetooth speakerphones?
