Upgrade to a Single or Jump to Double Boiler?

As the title states, I’m looking to upgrade and want to know if I should get a single boiler or just spend a bit more for a double.

Currently I use a Bambino Plus, I have a DF64 grinder. I have a little extra money, and I want to do something nice for myself and upgrade my machine.

I currently make 2-3 drinks a day for myself sometimes more if it’s a long day lol. Mostly lattes and cappuccinos but I drink straight espresso and americanos often too.

My partner also has a few drinks, but she doesn’t care as much for the quality as I do 😆

Currently I have a Profitec GO in my cart, but I’m wondering if spending a couple hundred more and just being done with it is a better idea.

I don’t need anything crazy as this is just for home use and not really doing crazy volume, but I’ve heard the double boilers are really nice if you’re doing milk drinks.

Just wondering what everyone’s thoughts were. Should I just get the GO or should I spend a few hundred more on a double boiler? And what are some recommendations/experiences if I do?

Thanks all!
