As for kits, thats a long list, but it all came out of my bitz boxes which makes me wonder what else is in there.
As for time, about six hours to assemble and four hours to paint. doesn't sound long I know but the planning and gathering of bitz is what takes the most time plus this was the second one I've done so it went a little quicker and the painting was about 80% dry brushing. I also did this while working on commission jobs so getting it done at all is amazing to me.
here's a pic of the last one I did which sold for $700 and was half the size.
funny thing is this is not the biggest model in my collection.
