Purchase recommendations

Here's my scenario with which I need some purchase advice from those that run multiple printers.

1. First thing is I have $400 in giftcards from makerworld
2. printing in PLA/PETG exclusively, but thats more because of point number 3
3. Already have 3 A1 combos in my farm
4. I print and sell boxes for trading card games, and insulin pens.

so with the gift cards I can just add a fourth A1 combo, but I'd like to expand to other materials if possible. I don't actually need the combo since any multi color stuff i can do on the other A1s. What I really need is a workhorse to pump out the basic shells in petg-cf etc while the A1s do the pretty stuff. I often find myself stuck because an A1 is printing back shells for 12 hours and I need to quickly run off some art.

If I get another A1 i don't have to worry about parts and maintenance as much. A p1 is tried and true and is basically guaranteed to fit the bill... and it's what i would have bought a month ago. the p2 is the new kid that seems to be an improvement on the P1 is every way, but it's on backorder. I can stretch out to wait for it, but don't know if it's worth the 150 for what I want to do.

adding either of the P's introduces some maintenance issues as i will need to keep other parts on hand, and i will become reliant on a machine that has no backup until i make enough to add another.

so what should I do?

• Go with what I know and keep it simple (A1 Combo)
• Go with what I need and and be able to expand in other materials (P1)
• Bite the bullet and get what I think should be the best (P2)

Thanks for reading.
