What do you thing about this grill? One at WalMart for $28 - Basic charcoal - two racks. Is it good for a beginner? What modifications should be made? For the price would I find out if I can do this smokin thing or would I be better off starting with something else? A gas or elec. for less frustration? Is the learning curve to much for a beginner? Is there a thread that covers this unit? I know I am asking a lot of questions but I want to try this smokin thing and not sure where to start. HELP!!!
