What are the recommendations for 8x8 and up? I prefer stickleress but not a deal breaker over quality. Well 8x8 and up to a reasonable size. Not gonna drop hundreds of dollars for the crazy 21x21 or anything.
Also interested in non WCA size megaminxes. I really enjoy megaminx so I want to try different orders.
For 8x8 and 9x9, Diansheng has magnetic ones coming out very soon. They are likely to be the best. If you can't wait, get the Cyclone Boys G8 and the Meilong 9x9. For 10x10 and up, the Meilongs are probably your best bet.
For higher order megaminxes, you really only have one option - Shengshou. MF8 made some as well but you don't want those.
