The PC has only 1-6 on the speed dial.
Oscillations per minute.... No idea. I have found wonderful results by JUST using the PC with the correct pads and polishes.
I also have a PC 7426 (True rotary), but use the PC 90 % of the time.
Cleaning the pads are easy, just put some dawn dish liquid in the sink and let the pads soak for 20 minutes, rinse clean, dry and store in a plastic bag.
As for the price being to high, the more people the bigger the discount. I am pretty sure we could get a 25% discount with 25 members.
The PC at other places range from $99.00 (IF ON SALE) to $$225(meguiars).
The pads that come with the PC DAS or SFX are top rate pads with Velcro backing that doesn't come off like other pads(I'm not saying it wont but it doesn't happen very often).
The backing plate is much nicer then the one PC gives you.
I still feel its a great deal if someone is looking for one.
