Is it worth it to convert my BBQ grill from propane to natural gas?

If you don't use charcoal I don't think it really matters. If you could convert it to charcoal I'd jump on it. I've tasted a lot of food cooked on gas and over coals. I've cooked on a grill for 33 years now and I've never tasted food cooked over gas that made me want to change. If all I could use was a gas grill I'd just do my cooking in the kitchen.
