Ok, I'll bite what's a "SCMS's?"
I own lots of Makita, Hitachi and Porter Cable. All of it is high end stuff but purchased for different reasons.
The Porter Cable is a circular saw that I purchased because it was as accurate as a circular saw could be _and_ it was left handed. I find the motor technology to be robust but outdated. The table is magnesium and very nice but fragile. The mounting system, well, let's just say "don't drop it."
I own two Hitachi M12Vs and the 14" sliding compound mitre saw. All are really nice stuff. Robust, well designed stylish if not almost pretty. Fit and finish is very good.
I collect Makita. They use a unique 4 pole motor technology that allows a reduction in the size of the motor and thus the size and weight of the tool. I didn't buy any of it. It all just kind of "fell" into my possession. I had a Sears electric drill and it croaked and any attempts to resurrect it were futile.
I stopped at a Saturday garage sale and low and behold a Makita drill. I offered the guy $1.25 for it and he said sure and handed it to me. OOOOOOk! I ran like hell thinking he might realize what he'd just done. I got it home, plugged it in and nada! I figured I'd just spent $1.25 for nothing so I might as well learn from the experience. I undid all of the screws and it fell apart into two neat halves. One half was perfectly clean and the other half had everything neatly arrayed in front of me. It took about 10 seconds to see the problem. The cord had been cut right at the cord protector. I shortened the cord and re-installed it. Plugged it in and ZOOM big time. Everything worked - variable speed with speed lock, reversible, keyless chuck. I was surprised and thrilled.
Next week a different garage sale another Makita drill - I offered the guy a buck he held out for two. Same thing, minor repair, another drill to add to the collection. One of the garage sales the guy had a very heavy hammer drill. No plug on the end. $1.25 later got it home, new plug - zoom. Everything works like a charm. I called Makita ordered a manual (free) and a cord -- Zoom! I now have a very heavy-duty variable - two speed, reversable hammer drill.
Other drills, reciprocating saws typically go for 1-2 bucks. The router on the other hand -- I had to work for that one. 3601B for $12.50 _but_ it didn't need any repair.
I'm now gradually getting rid of Dewalt, Black & Decker, Skil, Milwaukee even Porter Cable and replacing it with Makita, Hitachi (tools only - I don't like other Hitachi divisions) and Bosch. (I don't own any but they always come a close second when I go to buy something new. They just seem to have one less feature when everything else is equal. Bears consideration every time.)
There is one ringer in all of this. Ridgid makes ok stuff but then they went and put a lifetime guarantee on it. At certain times of the year you can buy a Ridgid battery powered drill and get a lifetime guarantee on the battery. I'm not nuts. I figure if I buy one and blow the battery every few years even if they go bust I'm still good for several free batteries. Pretty good buy -- except Makita of course ;-)
Makita - worth the investment. Harbour Freight? well let's just say "disposable!"
