I've been building Revell kits since i was 8 years old (im now 54) and i love them. The old ex monogram stuff usually has some fit issues and raised detail to rescribe.But thats part of the fun for me.On the plus side they have very good interior detail that in my opinion compares well with modern kits.Ive built a few Tamiya and Hasegawa kits which are superb.But they havent left me with the same sense of satisfaction as kits like the 1/48 Black Widow have.
