The Dewalts are decent and can sometimes be found on sale which I don't see on Bosch but maybe it's just the area I live in. I got one of my Dewalts for $50C, another for about $70. I never see the Boschs that cheap. I have 3 Dewalt orbitals, one PC, and a PC 1/4 pad now. I've adopted the idea that it is better to change sanders than it is to change grits. The velcro pads wear out and they are a bit pricey to change.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
