I had the opportunity to use a Foredom Buffer and thought that it left a better finish than my cheap Harbor Freight buffer.
Upon close inspection my buffed work had large scratches. So I was on a quest for a used Foredom Buffer. WOW - even used ones are $200 (when you can even find them). So, I got to thinking, "What's the difference between my cheap-o and Foredom - besides the obvious $200?" hmmmmm. They both spin at high speeds, both have variable speeds, and both have muslim buffer pads. Ahhh, my pad was purchased somewhere but wasn't a foredom buffing pad!!! So I ordered new pads from boredom, Yoohoo.
Only other difference is the size of the buffing pads, but the scratches are gone.
