I am thinking of getting some more Snap-On Die Grinders. I need some info . I currently have a Blue-Point angle head AT 110 and Snap-On PT 200 that I have had for years. I was thinking of replacing the angle head Blue-Point AT 110 with a Sanp-On PT 210A or should I get the PT 410? Are the smaller Snap-On Mini PT 100A and PT 110A good to also have or would they just stay in the tool box if I were to get the more powerful ones? Would a Snap-On PT 110A be about the same as my Blue-Point AT 110? Should I stick with my PT 200 or get a PT 400? I know in a perfect world it would be good to have all of them (spares, etc.) but at the same time, don't want to fill my box with stuff that I would not be used. Thanks!!
