My first build had generic Cherry-clone stabilizers, and they were pretty crummy. Since thing I've gone to the trouble to hunt down the renowned "Original CHERRY quality" stabilizers, and they have been better. But, honestly… I find they're still kind of ratty.
I've heard about people having problems with the wires, where they are not bent to a consistent span. I haven't noticed that so much, but the molding of the plastic parts is dire. The plastic surfaces are rough, their motion feels gritty, and a lot of them have bits of plastic flash that I have to carefully trim away with a pocket knife. I have to carefully test the fit of each stabilizer that I assemble and then trouble-shoot it before putting it onto a board.
Would somebody out there please, please give us a better quality stabilizer? Kaihua? Gaote? Gateron? For that matter, could CHERRY step up and give us some retooled stabilizers?
