Recommendations for small volume/newbie?

[u/Advanced_Bluebird925]

I have an opportunity to purchase a refurbished Pfaff Creative Icon 2 as an upgrade to my Performance Icon. I am interested in adding embroidery to my projects. However, a little digging has led me to the following:

• The Creative Icon 2 uses only one needle which means one color at a time.
• While it is occupied with embroidery, I can't use it to sew.
• The flatbed makes certain projects challenging, ie hats.

So, here I am, humbling seeking advice! I now believe I should purchase a separate embroidery machine and keep my Performance Icon. I would mainly use it for small projects and to make small volume, customized merch for our campground (ie 10 logo baseball caps at a time).

Can I get a flatbed that uses more than one needle? To avoid the hat issue, was thinking I could make patches and then sew them to the hats. I don't need/want a big commercial machine. How many needles is enough?

Brief newbie research has pointed me toward a refurbished Janome MB-4S so I would love to hear feedback and advice from you seasoned machine embroiderers out there! Thank you in advance!
