Man! I really hate that you're having this experience!
Would you mind my asking what it is you don't like about the build quality?
I feel like a reliable list of materials is a big factor here, in regards to the Kabuki not being made of mystery Chinese metals, or cheap plastic tanks...at least that's the biggest factor for me.
Is it the design of the tank you don't like? I'm just trying to figure out what's got you down on it, cuz I feel like it's a very simply built device...less parts, easy to maintain, easy to use...but again, this is all my opinion/experience with the Kabuki.
Of course to each his/her own...but I'm the only person in my circle with a Kabuki, so I have nobody else to talk to about it.
