littlejohn, I used it last week for the first time...a fellow Autopian lent it to me to try. I had it for several months in the box without trying it because I was unsure how it would work, and I didn't want to use a customers car as a guinea pig.
Well, I ended up using a customers car as a guinea pig! A '63 T-bird with rock-hard oxidised original metallic paint! My PC wasn't cutting it (literally). So I broke out the Mak. It worked very well in 'forced rotation' mode. It rotated like a rotary, but kept it's random orbit as well...no swirls or burning paint (probably equivalent to 900 rpm on a rotary). It had much more cut than the PC on this paint and eventually returned some shine to the finish. I used 1Z Extra (sand-in-a-can) and it left no marring and restored gloss. (Don't try this on regular paint...this paint was like polishing granite, and thus, was an exception).
I loved it...and hated it.
I loved it because it was harmless to use, yet returned almost rotary results. I hated it because it was top heavy and very tiring. It's also noisy (gearbox noise), requiring ear muffs.
I was totally wasted by the end of the day. I went back to my PC and it felt like a feather...although the Mak is only one pound heavier, it's weight is concentrated at the head, where-as, the PC is wonderfully balanced. It was like carressing a puppy after being mawled by a rottweiller.
In RO mode it was far weaker than the PC...no comparison.
In conclusion, my take is this:
One cannot compare the Mak BO6040 to a PC...they're too different. You'd buy one for it's 'forced rotation' mode, not its RO mode. In RO mode, it's great for applying paint cleaners/glazes/LSPs. One wouldn't use it to remove defects. You'd go to 'forced rotation' for that, and it *really* works! It leaves the PC behind in it's speed and gloss creation. It really is half-way to a rotary.
So, you must decide if you want to go half-way to rotary results with PC safety, or all the way to rotary and use the PC when you want safety.
Me...I'm undecided. If it was as comfortable a PC I'd say "YES, the PC can't touch it". But it's soooo not comfortable.
I haven't used a rotary so I can't compare it's ease of use to that of the BO6040. If a rotary is as tiring as the BO6040, I'd probably say "buy it!"
But I don't know~! :nixweiss
