I've used a Porter Cable 333VS 5" ROS for many years. I like it, but most annoying is waiting for the thing to stop after switching it off. The pro-5 stops nearly instantly (a slight lag on startup that is slightly off putting, but I'll deal with it).
The vibration, or really lack there of is also a very nice change. The sample pack of the light blue Garnet paper seems to live up to it's reputation. Nice big power switch, comfy grip, what's not to love?
The ROS one of my most used power hand tools, I think this was $200 well spent. At least I have a year to decide if/what the $50 voucher will be used on (probably for "system" accessories that no Festool user would be seen without 8^).
