Im looking at getting either a f90bt or an x910bt. I have been able to find both around the same price and i have a few questions. Does the f series really have that many more problems than the x series? WHat about a refurbished f90bt? and also i cant seem to find any pics, but does the knob light on the x910 change colors with the rest of it? i have only seen pics with it blue, and that will contrast with my interior. thanks to any who help.
