Interesting topics.

1) Safety is to be considered no doubt, however, if no heat or flame around, should be ok.

2) Money is something else. I started doing models early 2023, and even if most of my models are not in the very expensive range (most expensive one is my F-16, 1/32 scale from Tamiya and cheapest in the M1 Abrams), money spent for paints, tools, decals and other is probably pretty substantial. And my last idea of building a battleship is not going to reduce those expenses... Anyhow, building those models makes me feel relax (most of the time!) and without any doubt, it is more interesting than watching some non-sense movies, even so, I do enjoy watching a good one. So, I would say, for me, it is money well spent
