+2 on McFeely's even over here in Japan
I do buy most of mine at Joyful Honda or Super Viva Home, but there are always choices, I NEVER buy the cheap ones on sale, and I look to see where they are made. The cheap head poppers are almost always made in China, where as the ones made in Japan, are usually better, but more expensive. I am willing to pay a bit more to avoid the frustration that you speak about.
