Tested the ¥108 router from Daiso (purchased this at Daiso Harajuku, JP) last year.
It's not as powerful as I'd like but it's great for small projects and soft wood material.
This mini router also comes with compatible parts.
This is a mini drill bit (2.34mm diameter) which I prefer to the actual router part. My advice- drill then rout.
Anyway, this mini router is also available here in Singapore. Get it while it lasts!
