Caldercraft are a British independent company and nothing to do with Krick. They are 'older' kits and the parts, method of build etc. reflect that. The cost to 'bring them up to date' would be prohibitive. They are not a huge conglomerate with a factory workforce - much like the rest of the British model boat manufacturers they are a small family concern who have supplied the enthusiast for years.
We, at Linkspan, are fairly recent to the manufacturing scene so we have had the chance to embrace the modern technology. Our drawings are all CAD produced, the superstructures are laser-cut for accuracy and the vast majority of the fittings are 3D printed using the sintered powder technique not the filament type - a not inconsiderable investment! Our philosophy with out kits has been to design them such that they can be a pleasure to build, fit together well and are less likely to end up in the bin because of frustration. Unfortunately, this technology comes at a cost which has to be recouped but, we have been told on a number of occasions, that our prices are not extravagant for what you get. I will leave that view to those who have bought our kits!!!
In the end, you pays yer money and takes yer choice - and yer choice has to be based on the prototype of what you want to build.
You wont find a car ferry kit at Caldercraft or Mountfleet Models!!!
