For me, it's the Japanese basses. Yamaha, ESP, and Ibanez all can build amazing instruments in whatever price range they choose to compete in.
Their problem is their marketing, while international and in particular here in the US, is just screwy with limited availability, and a Japanese mindset. Go to Winter NAMM to their huge stands, and you'll be thrilled by what you see. Then you wait . . . . and wait . . . . and wait . . . . . and wait . . . . . for available for purchase pieces either online or at a large retailer. Or if it's NOT one of the models Guitar Center ordered in the hundreds of pieces. Try and lay hands on a neckthru TRB. You can buy Easts or Patituccis from the dealers that are stuck with them, but that's it. Substitute ESP or Ibanez in the example if you're looking for their high end models. Sure you can buy the budget ones all day long (at least for a while . . . . . ), but the big ticket ones are almost Moby Dicks.
Then to aggravate things more, the Japanese roll models over and over, almost yearly. They rarely if ever take a given model and slowly develop it or even just sell the same thing over a several year period. This year's Soundgear is likely different from next year's Soundgear. BB Yamahas now are nothing like the 80's gems. ESP is all over the place with their model mix. I firmly believe they short-change themselves with this aggravatingly 'iffy' availability. I firmly believe the Japanese invented the 'back-ordered until discontinued' business model.
It's a cultural difference I'm sure, but it's always made me crazy.
