Hi, sorry I forgot all about it.
I did visit Ari Ben and EFT back in May.
The answer is yes, you can go to Ari Ben and do you FAA training, then to EFT to do your JAA conversions. In fact as far as I understood it, people who are on the EFT APP course are taught by Ari Ben instructors whilst doing the FAA training, its just $20k more expensive for some reason.
The schools seem nice, a little small, it was very busy when I visited. Overall the students I spoke to were happy with Ari Ben, I didnt meet students from EFT, but they are in the same building.
I have made the decicision not to go to Ari Ben or EFT just down to the fact that I didnt like the area, Ft Pierce is not very nice (sorry to anyone who lives there) and I was planning on spending 2 years in the States, so havibg to live there was not an option for me. Apparantly most of the students live in Vero Beach, which is very nice, but I couldnt really afford a car to drive down each day.
Only a small problem, which probably wouldnt put most people off
I suggest that you take some time out and visit as many schools in the USA as you can before you spend any money on training, its a large investment you are making, and youve got to make sure that you are 100% happy with what you are doing, if not, dont do it.
Hope this helps, if anyone has any specific questions, I will try to help (please remember though, I was only there for 2 hours)
