Depends on how much you're willing to spend. The ones on BudK are all junk with the, out of place, exception of their Benchmade line-up which are some of the best OTF's and range from $250-$450(add, at the bare minimum, another $50+ for taxes and shipping). Personally, I think, with all the mechanics involved in an OTF, it's not worth the price tag because the more "mechanisms" you put in a knife, the less reliable it becomes, which is why a fixed blade will always be more reliable than a folder or an automatic of equal quality. Especially since I'm not a mercenary or an assassin. OTF's are definitely cool tho. So, as with any knife, if it's for show, buy cheap. If it's for survival, dip into your savingsFrom top down, these knives are in order of reliability.
