asin58,
Sorry!

I do not have any ill intentions. I just thought I share with everyone what I saw in the hobby store here at San Jose, CA. They look very similar to what you have in the photo, so I used it to show how expensive those parts are.
It's wonderful that you have the knowledge and tools to DIY parts. I wish I can do the same thing.
I left Taiwan at 12years old and grew up in US. Over the years I lost my Chinese written skills.

I usually ask my wife to type Chinese for me, however, I am back in US for 2 weeks, so I have no choice but to use English.
