I had the Masters
TC-20t and it started having problems within the first year. The air pressure in the tank had to drop to well below 10psi before the motor would engage. I do admit, however, that it was the first compressor I ever used when airbrushing. At the time, I didn't know that compressing air caused water to accumulate inside the tank and not just inside the moisture trap. As a result, I never removed the plug from the underside of the tank and/or the clear cover from the moisture trap when I finished a session.

I'm sure that the inside of the compressor was mostly rusted through before it started to fail. I can't say for sure that the rust was the problem, but I can't imagine it helped either.
Regardless, I decided to upgrade when I bought the new compressor and went with the
PointZero Pro Airbrush Air Compressor Twin Piston w/ Tank 1/3 HP. It cost about $130 on amazon and has run like a champ for over two years now and is strong enough to run two airbrushes at the same time at ~20psi each (maybe more, I haven't tried). I do remove both the clear cover from the moisture trap and the plug from the bottom of the tank after every use and have noticed no rust.
I don't know about the other two compressors, so I can't tell you how they compare. I'm also not sure about availability/shipping to Sweden, but it's a great compressor if you can get one.
P.S. - I also have an Iwata
HP-
CS and it is by far my favorite for every application. I also have a Krome and an Iwata
HP-
BCS and neither see much use because the the
HP-
CS is such a workhorse. You made an excellent call with that one!
