I don't really have a crib recommendation, but I did have a little beaver for my second and he chewed up the side of his crib. Not bad, but still... he chewed it.
He wasn't in the crib until 8+ months and only for naps. We're using the same crib for this baby. I don't think it has non-toxic paint, I don't remember specifically looking for it so I can't be certain. After DS2 put some teeth marks in it I bought those plastic things to go over it. My first never ever chewed his crib. To this day, I blame myself. I remember hearing him up, cooing and making little sounds. He wasn't crying, so I left him be and finished cleaning up. Had I just gotten him out and tossed him int he sling like I normally would, he wouldn't have chewed it.
Honestly, I wouldn't spend the extra if the price difference is significant... but I suppose it depends. We have never really used cribs that much and DS2 was out of it at a year, so it got a few months use, if that.
