Depending on the price I wouldn't be opposed to purchasing it again today depending on what I'm needing in a camera.
I come from a very hyper budget background where I used sub $1000 Sony handy cams up until about 5 years ago. For me what's important is getting the most bang for my buck and also versatility. For me the LS300 was, and still is, an ideal camera, one that allows me to use it as a camcorder AND as a cinema camera, while giving me SDI out, a log profile, XLR inputs, ND filters, etc. While you could achieve this with other cameras, having it all in one package is incredibly convenient. And getting that package for under $2500? That's pretty impressive, especially when you consider how well JVC supported it even after it didn't make a huge splash on the market.
It's not my only camera, I have a GH5 and G85, but I still see myself getting quite a few years out of it.
