I have (so far) been mercifully spared by the photography bug, so I’m not sure where it falls in terms of cost, but keeping inverts can actually be done really cheaply while still providing very good care. Now that I’ve said that…run for your life, lol.
I can’t really speak to insects, but I do keep tarantulas and have really had to set firm bounds on myself. Not just money-wise (because oh, the beautiful terrariums you can build), but also in terms of what I can reasonably care for, what I reasonably have space for, etc. That said, this is probably the most fun I’ve ever had with a hobby. I have two prepping to molt as I type this and I feel like it’s Christmas morning.
I think we might be kindred spirits. The stuff I own because suddenly Hobby X was the most critical thing in my life… There is a recorder (the instrument) sitting on my desk right now because I decided a couple of months ago at 2AM that it was high-time I learned to read music. Thank goodness I didn’t buy a violin.
I took a couple photos mid-molt today, but they are so stinking blurry. It’s a mix of low-skill, low-light, a phone camera, and trying to photograph through reflective enclosures, I think. I have thought about looking into better equipment before, but having read your story I don’t think that’s a good idea!
