I've got the Bosch - never had any trouble.
It can't be compared with a true cabinet saw, but for portability it's hard to beat.
Have had it for a few years now, so haven't shopped lately, but at the time it's fold down stand was the best out there.
fence system has never given me any trouble - again - it's more a portable job site saw than something you'd use for fine furniture making - but in its class, I'd rank it right up there at the top.
I know there are some plastic parts inside that make people nervous - but I think that's true for most of them. And I've never had any trouble whatsoever - so, can't really say what would happen if something broke.
it's a good saw. I've gotten my money's worth out of it, and I see no reason it won't be with me for many more years.
