Gluing Up Projects, Ender 2 Pro Upgrades, Which Printer To Buy and MORE!!!

This Episodes Questions:

I want to put a touch screen on my ender 2 pro without any knob on like I have on my ender cr-6se and was wondering if you know if I get a cr-6 one would it be plug and play?
Is there a community firmware for the ender 2 pro?
Thanks, William

I am looking at buying a new printer for myself as a Christmas present and right now there's two big questions in my mind. One is the Qidi plus 4. Seems like everything I want on paper with speed, accuracy, build quality and most important to me - Is its ability to print high temperature materials with the heated chamber.
I am designing parts that could benefit from some more exotic materials like PBT, PP-CF, glass filled ABS etc. I know that there's a recall with the heater heated chamber relay on the plus 4, but it really does look like they're gonna make it right for customers. They're gonna give what's needed to repair it. I'm not concerned about repairing things, it's  easy for me to do a little bit of work for some maintenance and upgrades over the years.
On the other hand, I'm really really enticed by the new K2 max. I don't particularly need its larger volume. K2 max does a lot of the same things that the plus 4 does as far as high temperatures and heated chamber and the K2 max seems to be from a brand and a company that's a little bit more trustworthy. I don't particularly want the multimaterial system, I don't mind changing filaments. I am concerned about the price. It's $1200 versus $800 and I love the idea of longevity, maintainability and buying something of high quality and having it last for years longer so maybe reality is the right answer for me but, wow, that $400 difference just is really hard to justify going all the way up to that Creality K2.
What other differences should I consider in my decision?
