Granted they are not as well put together as a KTM or later Samhongsa mechanism, but then, they cost about half of one of those. It would seem NAPM has not had the reliability issues that the WC has. I will agree with you that they are not the most user servicable models out there, but I'm afraid that is going to get more common as manufacturers try and hold costs down, use cheaper materials, and design models to be manufactured efficiently which sometimes leaves out repair. I'm sticking to my older brass and installing tsunamis though i would not rule out BLI if they made something I wanted (except a GS-4...plenty of those on hand!)
Those Spectrums are the only non-brass I own except for two Bowsers & two MDC's. As you know every other loco I have is brass. Which are designed for user repair. The Spectrums are surprisingly easy to work on. NWSL can supply any combo of gears needed as the Spectrum axles are 3mm, unlike BLI's which vary between 4-5.5mm, depending on engine. Another reason not to buy one. What if they went OOB tomorrow? I seriously doubt that they would have the lifetime of my Akanes, or your Max Grays'.
