Best machines on the market? (single head/ multi needle)

I hope I have come to the right place! Looking for the top 3 multi-needle (single head) machines. This is for light work, so I don't need a workhorse as much as an enjoyable-to-use machine. I love all the new technology I've heard about, so I don't want to get a model that is older and doesn't have some cool things. I know some of these machines go up to 19k MSRP (I guess around 14) and also looking at used too.
Thank you in advance! It's so confusing because the machines sort of 'look alike' and I can't really go look in person at every single model available. I've been researching online for weeks, but it is confusing!
