My tuppence worth if I may...I had the chance to get my brother-in-laws very cheap when he upgraded. A Voxelab Aries. Decent beginner model, comes already built, easy enough to use, incredibly difficult to master!
I have however made some equipment for my modelling, from freely available files.
The paint carousel in particular is such a space saver and extra levels can be added easily. Also some bottle holders to help keep workspace just that bit more organised. These can also easily be scaled up/down according to bottle sizes.
TinkerCad is a great free program and fairly easy to get a grip of for simple designs you can do yourself.
I've also printed off some 1/35 accessories, ammo boxes, fuel cans, weapons boxes etc to add to my builds. I would struggle to make anything smaller as the detail would just not be there, and that's the limitation of filament printing.
I know it's something I'm finding useful just now but I also know I'll run out of useful things to print very quickly, at which point it'll be rarely used. I would definitely go the used route if you can, and if you decide to upgrade later then great. If it becomes an ornament then no great loss.
