It varies by brand. Plato pretty much runs forever. Kant, even property maintained, will leave you scratching your head. People keep Aristotle running, but it’s not pretty. For what you spend Hume is a bargain—you can even take it off road in the forest...assuming there are unfallen trees. For the DIYer, Wittgenstein will keep you busy but Russell is known to have a computational design flaw. I recommend a late model Singer if you can afford it because they’re still making parts.
