I have a Daniel Boone and love it! they are a great unit that produce great tasting food and are VERY well built. The app for Android/iPhone is really easy to use and makes life a bit easier at 3am when you get up to put a brisket on! just set it up put ya meat on and go get some sleep!
Not sure what kinda price they are over there but i got mine pretty cheap - Got the Daniel Boone itself, the Cover (amazing quality its like leather), the skillet tray, the upper smoke shelf, a bag of pellets and a BBQ tool set (useless and poor quality but hey its free) all for NZD$1099 so you most definitely cannot argue with price.
I know that GMG are in the process of web-based control for the units so if your at your home PC you can log-in and check on things also.
I have found the built in Temp Probe is very accurate when tested against my Maverick ET-732 and also an OXO Instant-read so no complaints there
All in all i think they are an amazing pit and unbeatable in its price range, i would however definable recommend 2 things:
#1 FOIL the drip tray and bucket as cleaning this is a BITCH!
#2 Get the front shelf add-on as its a bloody useful as seen in pic below !
Hope this helps
