Yes I do ,I have not had a chance to use it with larger pads but it was fine when I tried it with 4" pads,mine only has 2 speed though,I bought it from Ebay off of a Canadian vendor:
NEIKO 7" 2 SPEED ELECTRIC POLISHER BRAND NEW - (eBay.ca item 280215908285 end time 13-Apr-08 22:27:08 EDT)
I bid and won it for $20!!,the machine itself looks like Makita ,11 amp, 2000/3800 rpm.
The first link seems to be exactly the same but with a variable speed, its not heavy at all,as I mentioned ,I do know others have had these machines for a few years.
BTW it comes with an extra set of brushes ,a cheap backing plate (ha ha),a wool bonnet a sanding disk.
I only bought it for the machine itself and have no regrets.
