I spoke to Inmotion and the local Taxas dealer for Upsolute. Upsolute was pretty honest in telling me that all the files that eveyone is selling is all the same. Beaware that these files are from Europe and so most of the performance quotes are in PS and not HP and instead of torque you will often see NM. Here is a good site that will convert these for you.

I will probably go with Upsolute because he is just 12 miles from my house.
