The Semroc kit is a new version of the Estes kit originally issued in 1965, one of the first scale kits I built when I was 10-11 years old in 1969-70 or thereabouts.
It came out very nicely. It's not hard to build the stock model and give it one of the White Sands black/white paint jobs, and have it come out pretty good. I wasn't exactly a Michelangelo with glue, x-acto knives and hobby paint in those days, but it still came out OK.
(And that was even back in the olden days when we had to CUT OUR OWN FINS, you young whipper-snappers!!!!! And the V-2 fins were a little tougher than most conventional fins, due to the curved root edge.)
Now, it's not a "fine scale" model, but if you want to invest more time into sanding, painting and detailing, you could make it one.
Between the Semroc kit, the ASP kits, and LOC's big-boy V-2 models, you should be able to find a version for any size of motor from 13mm up to the HPR monsters.
