What Was The Most Difficult Kit ?
I won't knock all e-bay specials. I know those AA (Nosen) kits are horrible because I have seen a few over the years but I can recommend those AK Models Mig29 e-bay specials you see every now and then.
First rate kit for a cottage industry guy. Laser cut, good fit (haven't finished it yet, though). Instructions are so-so but it's an easy build.
Got off topic by mentioning a good kit but just needed to be said that all the e-bay specials aren't bad.
