Sure, there needs to be entry-level products in any hobby. Take music, for example. I started on a cheap $300 drum kit when I first got into drums, and now the kit I use costs well over $5,000. No way I could have bought a $5,000 drumkit when I was just getting started!
Conversely, neither would I want to use that $300 drumkit on stage.
The hobby indeed needs cheap kits for beginners to get started with, but at the same time we cannot lie to ourselves and consider such kits to be on the same level as the more modern, more expensive, higher quality kits. That said, some talented modellers can take any kit and turn it into a gem.
I suppose the point of this reply is to agree with the point that we need cheap and accessible kits for youngsters to get involved in the hobby, but at the same time to defend people's opinions of low-quality kits (such as those offered by Lindberg).
One point about price, though: those same kids who can't seem to find the 45 bucks for a good kit don't seem to have any trouble finding 50 bucks for the latest PS2 game...
