Hi everyone
The cheapest is not always the best option. Quality is essential, so you have to look for the best rate.
I work as a FI in Spain, and JAR have been adopted since June 2001, you might want to check out the prices here.
I think obtaining the FI rating is a good option, that's why I did it, but it's not only to build time, you need to like it.
Good luck to you all!
