Guarantees are one thing, but unless you're in the same country as the camera's supplier, don't underestimate the costs of shipping back and forth if you happen to need to. It can get very expensive (especially to Russia or the Ukraine, where it's also not only expensive, but unreliable), and the savings on the camera itself can easily be eaten up by those costs. I saw an acquaintance's Pentacon Six TL a while ago. The camera body itself is actually a nice-looking design, but the film transport mechanism is pretty unreliable and very easily broken, no matter what "tips" you can read about it on the internet. I mean, like you're always going to remember not to let the wind lever snap back but to ease it back gently. Yeah right!
