That is exactly what we have all been saying on this thread. The price increase makes buying this first hand on the official price of 399 euros/dollars absolutely unattractive.
The second hand market is saturated with M:C and M:S, I do not believe their average prices will increase because of how many are available.
The model products are notorious for being really cheap build quality, specifically I have read lots of complains about the encoders getting mushy, the labels randomly getting erased as you clean up the surface of the products and the pads being absolute hell to play with random sensitivity trigger between different products.
The material support seems great, but the software support is nonexistant as both models have received no significant updates since their release. Sequencer is standard Elektron, which is great. But as I said, the liven offers the exact same sequencer.
Praising one product of a brand does not mean you work for the brand. There is a reason why the lofi-12 is currently Top 5 of the best selling samplers on Thomann… Same reason why the Roland SP-404 Mk II is up there aswell. And That is also why I specifically mentionned both.
