Since you built the elder, just about any newer popular kit from big names like Great Planes, Sig, Goldberg, etc. would be good next builds. Most all of them have plans, instructions, and precut wood (I am sure there are exceptions) that make them "easier" than some. After learning the kit building basics like you did with the elder, you can't really go wrong with any of these. Even if you get a kit that is one of the harder ones to build, you have the essentials to push through and get it done. To me, the only thing that makes one kit harder than another is not the complexity, but having to sand a little more or maybe even cut out or modify "some" of your own parts based on the plans. Don't let any kit intimidate you, you can get it done! Best of luck!
