I'm surprised how few Thomas compressors I see in the hands of builders, as Thomas not only owns the patents for airless compressors, they're one of the biggest and best compressor makers in the country. Thomas machines are the standard in applications like air brushing and medical compressors and aspirators.I bought my Thomas after reading a comparitive review in Fine Homebuilding, and I wasn't diasppointed. Build quality is top notch, and the machine is suprisingly quiet in operation. This pancake unit is ideal for a finish carpenter or two. Put it in the next room and you'll hardly notice it kicking on and off.
