If you are looking for Estrella parts, have a look at the Yahoo auctions in Japan!
Might be quite difficult to buy the parts if you have no connections to Japan - but if you have connection to someone living there, you might be lucky! But even the pictures and range are interresting for Non-Japanese people! Seems like paradise!
There is a text with a "50" at the right side (right above the "RSS/?"). This means: Show the next 50 parts.
