Yep, I second Real. I've got a decent touring helmet that's safety certified, relatively comfortable, and was only like 2-3k baht. The shape may not work for all so you'll want to try to fit first if you can.
Thanks all! This will be at the office in Central Festival Chiang Mai so probably just easy enough to swing through and ask on a free day anyway... or at least not a big deal to have to go back a 2nd day if they need all present.
I don't see that as a similar issue. English-speaking Thai often get paid more, and to have to service someone who can't speak Thai may necessitate having a bilingual (higher paid staff).
In America, you pay for higher-skilled stylists (though I give you it wouldn't be acceptable to charge a Spanish-speaker more for service in their language).
Again, I'd be curious if they charge Thai-speaking farang the higher price.
I can use my chase credit card here and get good exchange rates (I pay in baht) w/ no foreign transaction fees. If you have a card geared towards travel, it's not usually a problem.
