There's pretty much three tiers. the kind that cost like $25, the kind that cost over $200, and the Boker Plus.
The kind that cost $25 will start coming loose within days of buying it, and in a week or two will jangle like a set of car keys when you start flipping it around. The stresses that flipping places on their cheap fasteners will distort them, and no amount of tuning will fix them once that happens.
Good balisongs have better material, but they cost a lot not because of the material, which is usually simple, or the design which is usually also simple. they cost a lot because of how they're put together.
You are looking at one of the $200+ kinds, which are supposed to be indistinguishable from a real knife in terms of how it flips and spins. Benchmade is one of the best names in balisongs -- they got their start making them, but when I was shopping for trainers I never picked one up because they always seem to get middling reviews, which is something that worries me at a $200+ price point.
But I expect at least part of that is because they cost what they do. I would expect it to work very well, and if it started to not do so, I'd expect Benchmade to fix it for you. It should feel a lot more precise compared to a cheap trainer. Just keep in mind that all those three star reviews are out there, and it's your money.
I myself opted for a Boker Plus -- which is not the same as the Boker Magnum balisong trainer, which seems to fall directly into the 'cheapass' camp. But the Boker Plus trainer is solid considering it cost around $50. I've flipped it hard for several months now and all I've ever had to do to it is occasionally tighten the pivots again. It has a nice weight and a smooth, even action.
Without knowing more about your preferences, the Boker Plus is the way I'd go, but if you have stacks of benjamins burning in your pocket, go ahead and get the Benchmade and let me know how you like it.
