+1. Very high quality breakouts, albeit a bit expensive. Great support, and their Eagle libraries alone (free!) are worth spending some coin with them. Also in that category is Adafruit... can't go wrong with either one of them.For some components that they are reselling from wholesalers, they are a bit more expensive. But, they are a fantastic company to do business with.
Their breakout boards are really where they shine, really nice to get components with everything it needs ready to go. They also have a lot of good tutorials, and all of their stuff is open source. So if you do use their breakout boards you can easily incorporate it into a design later.
