Aussie Larks - thank you for the advice! At the end of the day, it's for fun(hobby) so mine isn't about Zen or professionalism. However, I kind of care about the attitude to make a product. It's just like I don't want to buy a product from a guy who overly express how easy to make things and people still want to pay top dollar on his products, so at least I try to do my best on my projects, not necessarily perfect.
Petey - Thank you! Yes, Hatagane is very convenient for small projects! and it seems like they reduced the price a little bit:)
