yes, I installed a Safe-T-Plus two seasons ago and it made a big difference... I love it
At the time I had the Roadmaster on order, as it was a little less money, but they were out of them and I was going on a long trip, so i cancelled the order and bought the STP
Easy to install, returns the wheel to center better, and the spring is enclosed (either stabilizer is right out front, so this may end up being an important advantage for the STP)
but FIRST you should set the caster as high as possible (see Harvard's posts)
