We are looking for the most realistic appearing gas logs for a masonry fireplace. We have looked at Heat& Glo and the American Gas log products. They are 'O.K'...but we understand there is a ceramic log variety. Is this more desirable than the composite? We would be giving up a wood-burning fireplsce.....is this a good move?? Or will we regret it ...for the convenience that gas logs privide? Thanks for the consultation!
