Raptor, Start with the last one, the Hetzer. it's simple and would be easy to assemble. the most important thing to remember is to be patient, take your time. one slip-up with, like with the glue, and it will show forever. like Ttasmmv said, clean all the parts thoroughly and make sure the mating edges are clean and smooth. dry-fit the parts to make sure the mating edges mate properly before you glue them. for paint I often use an airbrush as even the best brushes can leave brush marks, but that is personal preference. remember preparation is everything.
