First, let me say I know less about scrolling than I do about turning. And I am like Sargent Schultz when it comes to turning- "I know nothing." So I need to determine what I should give for a RBI Hawk 214-BT scroll saw. From what I read, this is a desirable saw, is it? Ten bucks, two hundred bucks, I don't know, so what should one pay for a used RBI 214-BT saw?
