> Without considering price, what is the best orbital sander to buy.
Bigger is better IMHO.
The sanding area varies as the square of the diameter, thus a 5"%, a
6"6, and an 8"d.
64/25 = 2.56, which means an 8" unit has 2.56 times the area of a 5"
unit, which means you spend less time sanding.
Obviously, an 8" requires more investment than a 5".
If you can afford the investment, look Fein, Festool.
If not, look at Bosch.
