IMUs - so many choises

[Mrman]

I've been doing a lot of searches and I got quite a few results from this forum so thought I might ask for your opinions.

I'm working on a new project and I'm only interested in getting the the orientation(9DOF), I won't be using it with a flight controller of any kind - just IMU+Arduino.
I want an IMU that's easy to use with Arduino, accurate(Uses all 9DOF to calculate the orientation, Low or no drifting) and not too expensive, I've recently came across this IMU: http://www.ebay.com/itm/10DOF-MS5611-HM ... 27c66b2c67
The components seems to be identical to the FreeIMU v0.4, could I use the FreeIMU Arduino code with this module? Its less than half the price of the original FreeIMU.
In addition there are the drotek, ArduIMU, pololu and many others.

Which IMU would you recommend for my needs? I'm not very talented when it comes to electronics/programming so I'd really like something simple.
Thank you.

can't help you with the rest,
but if you choose that IMU, it's 6$ cheaper here

Bought it myself today.

that IMU is already supported in the current dev code - its the GY_86 and it is almost identical to the freeimu 0.4.3 - it's a lovely IMU and one that I fly myself.

Thanks dr.tom, every penny counts

Katch, Good to hear, is there a code example that just obtains the orientation without the flight control part? I downloaded the code but I'm pretty much lost.

great imu! cheap and good components

in config.h all you need to do is uncomment #define gy_86 (latest dev) or you can use #define freeimu 0.4.3 in 2.0.

How do I get the orientation after that? I don't want to use/install multiwii, I just want a function/code that can return the current orientation and that's it.
