The giant spoon is 17 bucks because of metal prices. If you made one yourself, it would cost you $10 for the metal, and the take you 3 hours to put together by hand if you knew what you were doing. Your hourly rate would be worse than working at Walmart.
I was just in academy sports. They have a johnson sprite copy that is 3 inches and 3/4 oz for $2.29. If this were to actually take off, I could easily see copy cats come out by next season for less than half of what they are asking.
Let's just say I have a few of the Spoon's in my boat lol. I have spent the same for XD10'S and the live target baits. So yes I have spent a few buck's on lure's Do they work? I can't complain so far with them.
