I've purchased Pronto Uomo suits in the past (for as cheap as $30). While by no means would I call them high quality, I generally found them perfectly usable. My daily driver currently is a Pronto Uomo (85% wool). The cut, material, and stitching do leave what to be desired, and nobody is mistaking it for a Tom Ford, but it's far from the worst suit I've ever purchased, and I wouldn't call it completely unusable.
