I got in touch with him after he posted an ad for a used proportional Big Apple thermostat for $75. For better protection I asked him to take Paypal and he supposedly setup an account and send a request. It was paid and accepted on 6/23 and there has been no product or replies to emails I've sent every 5 days since then.
Finally I had to dispute the charge with Paypal and my credit card company.
His email addresses are
silverzero@aol.com and
gotblinky@aol.com which is the Paypal ID.
Just a heads-up to anybody dealing with him.
