I agree fully with FH. The SIG Kadet LT-40 is one great trainer. Great wood,instructions and plans. You will not be sorry you bought one. The kit also comes with things that others do not. As I recall it comes with fuel tank and wheels. Everything but the covering and glue. I may be wrong, so if I am please someone jump in. SIG kits are some of the best out there. The LT is also just a skosh bigger than other typical trainers. So it is easy to see. It helps out alot when learning. I have never heard of the Ibis trainer. So I will not comment on it. It may be a good one. I just do not know. Good luck with whichever one you get. And congratulations on the desire to build one.
