While I did not consider shipping costs a factor ($83 USD to send four A4000D motherboards by USPS Priority Express) to Anthony Hoffman in NZ an issue, his turn around time was about 6 days with a return time of 4 days; it took a bit over 2 weeks to get all four boards back in complete restored condition with a detailed repair report and thorough check. He repaired bad tracks, all caps, and recalibrated crystals. Very, very impressive, and which such a short turn around for 4 nonworking to perfectly working motherboards, highly worthwhile.
