I am just about sold on the Pit Boss, but will likely go for the Pro Series 1100 over the Austin XL mainly due to the handle to open the searing section, the front shelf and the fact they will assemble and deliver for free. That seems like it is definitely worth the extra $100.
There is one thing that I have read several times that is the only thing holding me back at this point, the hot spot issue due to no true heat diffuser. I know this is due to the searing option though which I REALLY like since you can't have a heat diffuser and still be able to open up the sear section.
I'm not so worried about PID vs. Non PID, or temp swings of +/- 10-20 degrees since realistically, your oven has temp swings too and that doesn't seem to effect the food. My old MES 30 had similar temp swings and it was fine so I'm not really worried about it on the Pit Boss. If I decided later that I wanted a PID controller I guess I could do that but I'd be concerned that would void the 5 year warranty. I'm not sure Savanah Stoker even makes one that fits this particular Pit Boss model but it looks like the
Rec Tec controller fits if you add a peace to cover the sides.
The hot spots though... I see a lot of people saying the left side of the grill is consistently up to 70 degrees hotter than the right side, with the right side closer to the read out temp. I wouldn't mind a difference of 10-15 degrees from right to left, but 70 degrees seems extreme. That is really the only thing that has me still concerned if I will be happy.
