Im in the market for a pellet grill. Do to budget constraints this is what I have narrowed it to. Looking at either the pit boss classic or the z grill 7002e or 7002b. Ive read alot of reviews on both but was hoping to hear peoples personal experience on here. Also it seems i can buy either of them cheaper on amazon or at a big box store. Is there a reason for this? Are they built cheaper than if I go direct through the company? Any input is appreciated from all. Thanks in advance.
