Hi Mike, and guys,
Most Korber kits are really a square box with a top. 4 walls and a roof. Yes there are exceptions like the round house or the grain silo that are a bit different, but most of the kits are pretty straightforward.
We have been working through the kits and updating the instructions to provide a more clear approach to assembly. We have been lucky to have some great help form modelers here on the forum who have helped with by contributing their tips and approaches as MikeCT notes (he was a big contributor to the new 304 roundhouse instructions) Many of these are posted on our website for download.
With respect to glue, we have had great success with the gorilla super glue (int he small bottle with a blue top - different than regular gorilla glue) this type of super glue has some "rubber" characteristics that work well and withstand some shocks.
Take a look at the models, and send me a note if you have any questions I will be glad to answer.
If you still feel uncomfortable with taking on a kit, we have several great model builders we work with (they are also listed on our site) you can pick one, or we can help you find one who will be glad to build one for you. We have helped several hobbyists this way get a great looking model that they may not have been able to get otherwise.
For those with nice comments, thank you.
