The main difference is the 110 has sapele back and sides and the 210 has rosewood back and sides. I haven't played the 100 series but I do have a 214ce and I think it sounds pretty good. People will say look elsewhere in that price range, but go play both of them and see what you like better.
Neither one is any better than the other. The difference is mostly cosmetic imo since the woods are laminate on both models. Both guitars sound very nice. I do like some other guitars better in the price range (as mentioned above), but these are both good quality and good sounding guitars.
Sweet, thanks for the help. On a side note, what guitars do you two prefer in this price range?
