depends upon what services you need. Non O + Multi entry permit + 90 Day Reports + whatever " help".... could be right. All depends upon requests made. I know they are a great firm.
But a DVD player here online through Lazada. Cheap and easy. Sure, a Chinese product... but for the price... why not. I had the same problem. My Thai bought old one (Otto brand) after 7 years died. New one is working just fine and even gives me a USB port... why I need one I have no idea....
Yes. One must renew before the old one expires. You can do that up to 14 days prior (though the time might be different depending upon your local office). Or you can fly out and come back in.
