I used to buy breakout boards from Arturo a while back but I think that his basic boards were copied and they are available from China now for a couple of $ each. Or perhaps Arturo was buying them from China originally, and the Chinese decided to cut out the middleman. I really don't know. In either case I bet his low end breakout board sales skid to a halt after clones showed up on Ebay.
