Yep, those ID kits can be a real drive from the rough.
I'd say that every manufacturer has their adherants. Some folks love the scratchbuilding stuff and would give a vital organ for the opportunities that an ID kit would present in large scale. Now that ID is out of business, Their kits are going to be sought after by those that love them.
ID kits were right over my head too. Years ago, a friend of mine was helping one of his uncle's clean out his attic and they found an ID 1/32 A-7 Corsair II kit still in its packaging. His uncle got it from somewhere and told him he could have it. A year or so later, having no idea even where to begin with it, my friend handed it over to me, still unstarted. I hung onto it for a couple of years, I love the SLUF and the chance to do one in 1/32 made me unwilling to part with the kit easily. However, after a couple of unsuccessful cockpit and landing gear scratchbuilding attempts, I traded it away to someone for something else.
Where it is now, is anyone's guess, but i hope it got built and whoever built it did it some justice.
