Seeking advice choosing a multi-color printer (sh.itjust.works)

Hello,

I am trying to figure out which printer with multi-color capabilities to buy, and I'd like to hear some other people's opinions.

Note: I can't buy Bambu Labs products, so please do not recommend one.

Current options:

Prusa Mk4 and MMU3.
Voron 2.4-style (either Formbot kit or Sovol SV08) and ERCF, and eventually DAKSH toolchanger.
Ratrig V4 and the upgrades when they come out.
Creality K2 Plus (when it comes out).
Qidi Q1 Pro and the rumored multi-color unit.

My current thoughts:

I am happy wait a bit if that's the best option.
I like the fact that the MMU3 mechinism doesn't waste as much filament as some other mechanisms. It's easier for me to pay more up front for the mechanism than constantly keeping tons extra filament in stock.
The potential for a Voron to be upgraded to a toolchanger with DAKSH is intising.
High print quality is important to me, although I can't imagine any of these would result in bad quality.
Prusa XL is outside my budget :(

Please let me know your opinions, and thank you to anybody who read this far.

My understanding is that PLA and PETG will not adhere together, so I guess if there's any residual PLA when printing the PETG it will cause it to not adhere fully. Makes sense and is a perfect example of where a tool changer would be incredibly useful.

I'm assuming you're using PLA to support the PETG parts because of their inability to adhere to each other? Don't know if you've seen it, but if you have relatively large, flat overhangs that need support, you can color in the top layer of the supports with a permanent marker. This will cause the same inability to adhere and you can snap the part off easy. Not really practical for multiple areas of support or if you need something like tree supports, but if you've got angular parts or similar could save a lot of time
