Well now, silly boy,
if you want a real buffer buy the Makita. Got it, love it. Does WAY more than buff. If you need to cover a lot of acreage it's the way to go.
Having said that, I gotta tell you Stu, I've got a HF air-compressor, drill press and an 800 watt generator that's about the size of a bowling ball that runs everything. A portable machine shop. For $200. Yep, it's cheap Chinese crap, the generator is louder'n hell (don't even think about running it in an anchorage), but I'll be damned, nothing has failed.
I got nothing bad to say about Harbor Freight.
