Bill sells some wilds and also tank bred. He also sells plecos, angels, cardinals.
Larry Forbes lives lives in Grayslake. I know he breeds discus also and most of his discus are from Bill's stock. He sometimes travels down to Naperville, where Bill lives. I'll contact Larry to get his phone.
I would avoid buying discus from LFS/LPS, due to the markup. Breeders are the best and cheapest source. I bought 3" discus at $20 each from a breeder, where an LFS/LPS would have sold it to me for about $50. It's your choice/money, so if you still opt to buy it from an LFS/LPS, be it.
