I am looking at getting one for installing moldings. Currently I have a local contractor do the installs and I get small kick back fir it. I am not sure if a 12 over 10 will give me much moer range or if getting a slider is better. At this time I have $400 set aside for it. Once my arm(4-5 month) heals I want to start doing my own install. Which style and models do you recomend?
