Ok, so I'm thinking it would be cool to get one of those accelerometers so I could measure my (and any one else who would let me

) 0-60, cornering forces, braking, etc...
What do you guys think, is that a waste of money to get one, I think it would be a cool thing to have...
I guess there are more of these accelerometers out there, but these are the two I hear the most about, G-Tech Pro and Beltronics Vector FX1.
I've heard mixed reviews of the G-Tech Pro, some say it is pretty good, others say it is really far off, has anyone used it, and what's been your experience with it?
G-Tech Pro
I read a review of the Beltronics FX1 and they claimed it was very accurate and really had nothing bad to say about it, I am thinking maybe its the better one, but does anyone have or use one?
FX1
