Not news to anyone, but Peter Lin of Big Leaf Orchids has the best phals! He has many great hybrids but I've also gotten a few species from him that were top quality.
In addition to his website, his "price sheet" lists even more species that you can email him to buy. Also check the ebay store.
I swear he's not paying me for this, but he did gift me a phal pulchra in spike when I drove 3 hours out of Austin to pick up an order
