> Moral of the story: Cheap is always expensive
Like when (in the mid-90's) we bought a bunch of PCs from a 'new' supplier in Korea/Taiwan (I forget which) called Trigem.
First batch arrived with 120v PSUs (with no warning - we had ordered 240v PSUs). Cue lots of sparks and the smell of frying electronics.
Trigem replaced them with 120/240v switchable PSUs. First batch, not a problem. Second batch, all the PSUs were set to 120v. Again, cue the smell of frying electronics.
We bought from UK suppliers after that.
