i did some hour building with them earlier this year, and have a few friends who trained with them. I dont want to get into the training in the USA discussion theres plenty on here about all that already, and i recomend you give it a read (taken with a pinch of salt).
I found RVS to be excellent, nice a/c, nice busy location, and an excellent management team that will look after you very well. they are very fair with everything and wont mess you about.
pm me if u want me to try and put u in contact with some x students.
