I currently work with Middle School students. I do expect a fair number of drops, bumps, and spills. It's photography business for the 7th grade today. A kit was was dropped and the bayonet on the lens was busted all the way around. Upon inspection of the body itself, it seems to work just fine. I can't quite inspect the entire function of the lens, but from the aperture I can see no visible damage to the glass or mechanisms. I can buy a used lens Canon EFS 18-55mm for less than $55 or fix the bayonet for $20 and risk something else being wrong with it as a result of the drop.

But Bou, it's six screws and an uncomplicated alignment, you could totally fix it. I imagine these kit lenses don't offer metal bayonets because they are built for mass consumption and/or to keep the prices down. I dig that. I do wish Canon made these parts more readily available to tinkers and hobbyists like myself so we can repair our own gear. 

None of the reputable dealers in my area will sell me a bayonet. If it was my own money, I would buy a bayonet and gamble that nothing else was wrong with the lens and that the bayonet was a quality part. But, I don't have to play this game. I'm going to replace the lens with a used one and hang on to this one until the next accident. We'll find out then if the lens is still good. Unless a kid shatters the bayonet again (sad trombone).
