We had the same fears regarding the granite. We went with a manufactured quartz, which was comparable in price to granite. They counters look great, and they have a 15 year warranty. Unfortunately, we have already had a dime-size piece chip out. The company came and patched it at no charge. It looks OK, but not as perfect as before.
I've also noticed that when I wipe my finger along the underside of the counters, where it's not glossed to a shine, I get dust on my finger. Thirty years from now there will be some health concern about that, I'm sure. I keep trying to tell myself that nothing is perfect!
The countertops we got were Green Guard Certified for indoor air quality. The ONLY reason we did not go with laminate was because of the off-gassing issue. I have read recently though that there are formaldehyde-free MDF boards to mount the laminate on. Not sure if that's true or not - did not research it indepth.
Good luck with your decision!
Oh, and be careful with some of the manufactured quartz. We were set to go with Silestone until I learned they are treated with Microban! I did not want THAT mixed into my countertop where we prepare food!
