I want to know if the old Planex model 575219 is random orbit or just spins. I see the old model on Recon, and figure for the price difference from the new model 575994 I could add some LED lights. However, I am not for sure if the old one is random orbit. I have never used one of these before, but think the RO would be a nice feature. So I would like to know if the old model is random orbit, and if not, if you think the Random Orbit feature would simplify operations. Will be used by inexperienced people on Habitat houses. Thank you.
