Per that thread, ddbump bought an Audiopipe 3k from him and he claimed he shipped it but provided no tracking info. Last I heard of the situation was that ddbump threatened him with filing a claim and he wishes to "wait to see what paypal will do." Just passing this along as the guy seems to do a lot of buying and selling on here.
Buyers beware. Either he's a slow *** shipper or a scammer.
