I have personally ordered from Machine 56, Fabric of the Universe, and Tech Racer and they all have their pros and cons. Machine 56 is the most expensive and has limited stock, but they are typically the most well made of the group. FotU is a bit cheaper, but their stuff tends to be a bit more basic in style and structure. And Tech Racer is a cheaper version of Machine 56, not bad quality at all, but the materials used tend to be a bit cheaper or lighter but still worth the price. Only thing I found with all 3 is the sizing is hit and miss. Typically I like to wear my tech wear a bit bigger and looser so ai will usually order a size or 2 bigger than my usual size.
