Upgrade? or Buy new?

I have a mostly stock Ender 3v2 from pandemic times and I'm wondering if it would make more sense financially to just buy something new or perform some extra modifications to speed up my print times. I did some DIY direct drive upgrades with the stock parts but asides from updated firmware and that I really haven't gone too deep into the customization space. I keep seeing good things about Bambu with its plug and play convenience but I don't have a good scope on everything currently available.

Currently I do a little bit of custom item prototyping and would like to start making more detailed items like DND mini's which require a level of accuracy my current machine cant really do.


If anyone has any recommendations or warnings I would love to hear what everyone has to say on the matter.
