Welcome. You have obviously found the class website. Here you will find all the links to other resources, a building site with the step by step Electronic Checklist that will take a beginner from planning to the water, a second building site with detail photos of boats around the class, the EC12Net for class communications and many other places.
Difficulty comes in different packages. While the EC12 is one of the larger models it is not very technical and many parts made for it so there is little crafting. This forum is a major resourse that compliments the building sites. The total time to build is greater but the actual work is about 60 hours.
A used boat can run $600 to $1000. Building depends on how much crafting you would like to do as part of the hobby. There is no kit and total cost can run $1200 to $1500. Some will tell you less but hardly for a beginner. If you are in an area of other EC12's there would be a chance of getting over stocked parts or used stuff. It would help here in the profile to know where you are so you could be pointed toward a group. There is much sharing in this class.
Having started with this, now I know you have 15 more to ask. [:D]
