Accelerometer Suggestions

[Donut]

Over the past week I've gotten the kit of parts accelerometer from last year working on the Vex for getting position and velocity (or it's mostly working).

Does anyone have suggestions for an accelerometer to use for inertial navigation on an FRC bot? The current one works on Vex, but I'm afraid it won't be able to handle the faster accelerations and speeds of an FRC bot. I like the MMA7260Q from Freescale, largely because I can choose the sensitivity that works best on it, but it's a 3.3V part and I'm not sure our team wants to deal with making a power converter (we have no skilled electrical students; we have 2 mentors but I'm not sure they'll have the time to do it).
