As a general rule, for beginning any new hobby involving any sort of implement (in this case a Balisong), get the best equipment you can afford. You can pick up a new Benchmade for just over $100 currently, so that would certainly be the way to go if it works for your budget.
Have fun, and welcome to the Forums!!
