For BGA, I would probably use the hot skillet method as I don't have a hot air station/gun. I didn't had the chance to try it out yet though...

Wow that's an expensive board :)

yes it is - and you can see how much are the chips themselves so - see where I'm coming from :) - you could probably make 5DOF, 6DOF and 9DOF boards much cheaper then those on sparkfun ..

Is there an actual distributor.  I saw the itg chip quoted as 15 in 1s, but I can't actually find anywhere to get any.

I see it here http://invensense.com/mems/catalog.html for 10$ directly from manufacturer (also there are "distributor" links too) ..

on the other hand, check this one out: http://invensense.com/mems/gyro/mpu6000.html - would be cool for making break board ... just I don't c a price anywhere ... http://www.cdiweb.com/FeaturedProducts. ... &NavType=1 .. maybe it would be cool to ask them for quote

btw - don't get me wrong I have NONE WHAT SO EVER EXPERIENCE with these chips! They just look "best" from the quick look on what sparkfun is offering... I never seen any of them work. I only used ADXL330 on the mikroE break out board (analog), and I ordered some analog gyro's .. so not only that I have not used chips I "recommend", I never used i2c/spi accelerometer nor i2c/spi gyro (I will soon receive MMA7455L from seeed so I will have a chance to ..)

No worries, I'm just happy to check out a new chip

just wanted to be sure I was not saying "I tried them and they are cool" :D ... for some reason I started with analog ones - no idea why... but I think digital are much easier to work with

Wow that's an expensive board :)[/quote]No kidding!  For that price, they should include a small USB PIC and USB mini port, and provide a whole programmable system for the same $65.
