I use a Canon G9X, which is a reasonably inexpensive digital camera that has built-in wi-fi support. This eliminates the need for a trigger release, since I can use my phone to remotely control the camera.
As far as lightboxes, I used to use a lightbox, but found that it was a pain to set up and heavily constrained what I could photograph (eg no army shots). I ended up ditching the lightbox entirely, and instead just getting a big sheet of black paper to use as a backdrop, setting it on my work table and taping it to the wall.
What the lightbox gives you is more even lighting, but you can do that yourself just by using at least two good light sources. I use
this setup, with the diffuser umbrellas being optional (they just prevent harsh shadows). I then set up my camera on a
cheap tripod and fiddle with the exposure settings to get the right effect.
These photos were all taken with the setup I just described, so judge for yourself.
