Hello. I am a beginner at speedsolving 2x2's, and I am looking to buy a Wittwo v1, since I have heard it is more stable than the Dayan 2x2 and is better than the Wittwo v2. Could anyone send me a link to where I can buy the Wittwo v1 (remember, v1, not v2)? I am unaware of which puzzle shops to purchase one at, or, which ones are reputable, for that matter.
