Would you buy it again?

Personally, I don’t care about multicolor. It isn’t important for the models I print. I got the AMS to use support material so I could print complex models with a 0 z-interface support gap and get better quality. It does work for this. One thing though - it can quickly turn a 2-hour print into a 6-hour print with all the required filament changes. And, there will be a lot of waste.

I find the AMS slows things down enough with filament changes, that I don’t usually want to use it. In most cases, if I can avoid needing support, I will design my model that way.

You can speed the filament changes up a bit.

These two changes halved my filament change times…which makes a significant difference when I do use the AMS.
