Not related to the post, i trained with a provider in South Florida that issued me then with a J1 wisa, that i used to work as CFI for about 2 years.
In that time i got enough hours to get my ATP. Out of my 1500 total time almost 1100 were on Twins.
The equipment was not always always in tip top shape, but for the amount of money I did pay, it was a great deal, and the large amount of multi time helped with finding a job after instructing.
Check them out, is not for everybody, but might be worth looking into it.
