I'm not sure what other machines are available to you in Switzerland but these CNC machines are rather small and will also be slow and somewhat underpowered, especially for cutting any metals. I put these in the toy category, and usually are more trouble than they are worth but might be fun to play with. Most people find them to be very frustrating because of their small size limits and underpowered drives and spindles.
I would recommend considering a larger CNC more in the hobby class that would have the power you want to do a few small projects in aluminum and should have no problems cutting wood items. These would still be a little slow but be heavier and tighter.
