Stick "light tents for photography” into Amazon and see what pops up. Different sizes, features.
I have one from LimoStudio. It was a gift, so I didn’t do any comparison shopping.
Side lamps were included, 4 different backdrops, small tripod with phone attachment, fold up nice. Costs less then a Tactical Squad. I think it was around $50, about 6 years ago. I like it, it gets the job done, but I’m no professional.
Things you want it to do:
Multiple lights from multiple angles. Being able to move them is a nice feature, to help eliminate shadows. Built in has the form factor, simple. If it doesn’t come with lights, you can just get some with some good bulbs.
Folding: Unless you have a large dedicated space, you probably want one that folds up. One perk of not just getting a cardboard box, cutting out parts, and using parchment paper to defuse the light.
Be big enough for what you do. I think mine is 16”, which is plenty for troopers, but getting a good shot of a flying hive tyrant or a stormraven was twitchy.
Backdrops: I just use a basic white one for everything. Other people change theirs. Options are a good thing.
This is the same mini/lights with different colors behind him:
Getting a lightbox helped me a LOT with my pictures. I don’t need to white balance them anymore, the only post production I do is to crop and stitch into composites. 2 big things are getting enough light and brace your camera. Once you do that you can play with fancy photo stuff like depth of focus, but a point and shoot camera (or modern phone) will do all that for you.
