About that Testors SBD, it's a good first glue-together kit for kids, the parts are thick and hold together well, so it can take a lot of punishment. Actually, that kit pretty much got me into the hobby.
I figure the worst kit I've run across recently is the Revell Gannet, no wheel wells whatsoever, no cockpit, just heads poking out, lots of flash, EEGGGHHHHHHH
