The only real negative as far as I'm concerned is the terrible original light boards for WoZ. They are ALL defective and will fail prematurely, it's just a matter of when. Giving owners a price break on replacements is *ok*, but given that they knew/know of the problem because it was a bad day-1 design, they should just send out a new complete set of boards and you send your old boards back and are done with it. The onsie-twosie nickel and diming on bad-design-from-the-factory, but-just-took-time-to-die boards is nonsense.
But that's it. They're definitely giving a MUCH higher build quality and a huge LCD screen for about 15%-20% more price. Stern keeps raising prices while at the same time cutting corners on build quality. THAT sucks.
