I've known Will for a couple of years through the local herp society and he's a very knowledgeable herper - gives great talks on how to determine the sex of snakes.
I recently bought a male piebald ball python from Will - actually in September. Will wanted to make sure the little guy had a few more meals and make sure he was fully switched to frozen thawed (which is what I solely feed) before taking more than a deposit.
Just took delivery of the little guy today and couldn't be happier. I'd highly recommend Will for great ball python morphs.
