It’s like if a guy lives in the backwoods and goes to car dealer and wants a 4x4 pick up but the salesperson says he has a great deal on a nearly-new Jaguar…
Well… kinda. If you shop around you can get a metal MagicYoyo N12 Shark’s Honor for under $20, heck, I bought them in bulk once (long story) and got them under $10.
I’m not completely clear on the question. There are certainly some yoyos that play above their price point. The Aviator 2 is absolutely amazing and can be found for around $20 on the BST. The Smoothie is probably the best all-around yoyo I’ve played and it’s relatively inexpensive for a bimetal. Yoyofficer makes some great budget bimetals.
