I believe the 1/2 sheets are more popular in Europe so someone from there may say RS2, in the US they will probably say the 150/3.
Oddly enough, in this corner of Europe we don't have the RS2! Instead we have four sanders in the RS series which look rather like it, and it can take a bit of time to work out the differences and to decide which one is best. Note the different motors, pad sizes and strokes.
