I know this is an old thread but in case anyone is interested in getting a dx2 delivered from the states, I got one through last week. Total cost this end was £60.
Very impressed with it so far. Used it at the weekend for some pork loin and whole chickens on the wsm so wanted higher temps than normal. It kept a steady 350 C which was not bad considering the thermapen showed about 6 C air temp. Going to try it out at a more conventional 225 C this weekend, just need to decide what to cook!
