Electrical Supply/Hardware Store

Try Manuel Gonzalez @ Piscinas,Equipos & Instalaciones. He installed a voltage regulator on our Casa 7 years ago and it is still working fine. He also sells pool equipment and can speak English very well. His store is located just pass the entrance to the hardware store on the lateral before you get to the last Pemex gas bar on your way to Ixtapa. I would advise you to phone him and arrange a time to meet him at his store as he is often out on installations.
His contact number is, cell 755 557 0480 or his office phone number is 554 9848. His staff only speak Spanish.
