My first and only problem purchase (MFJ-939I tuner) at qrz.com till date. After payment was made via PayPal, seller AC6CW began to give various reasons (began with car not available and ended with he being in the Philippines for cardiac treatment/surgery!) for the delay in sending my pkg and subsequently went silent. Contacted him via PayPal and extended time to send the pkg and when there was no response, I escalated the issue to PayPal as "item not received". PayPal worked quickly and few days ago I was informed that the case was ruled in my favor with the payment being recovered and credited to my account. This person could be a fraudster or someone genuinely in a difficult situation, so use your best judgement but cover your backs and use PayPal! This is FYI.
