I bought this 30 cm cube 1 year ago from my local store for something like 50$ (with shipping). Now it costs 300 PLN (about 80$). Maybe manufacturer just raised the prices.
I've bought some 3x3s, like Weilong WRM 2020, Valk Elite M, Tevgyun v2 M, and some budget ones to try out (like RS3M 2020, QiYI MS etc.). I may order some non-WCA stuff in nearest future.
I think that this competition can be continued. If someone wants to join/comeback/take a break, he can do it at any time. Pyraminx is my main event, so I'll compete every week (except I'm really busy)
