lol, zhuyin... how long have you been typing zhuyin? I pretty much touch type zhuyin ever since high school (like 10 years ago...). I did have to memorize a few key locations, like the accents. Once I got used to it, I never wanted any sort of chinese symbols showing up on my keyboard anymore lol.
And ya I also used to see keycap set from Ducky on PChome. Perhaps you could wait a little bit see if they will restock it later on, coz its got really cheap shipping rate oversea.
