The ET-732 was mentioned on a previous thread, but it is now possible to order one...
Maverick is coming out with a successor to their ET-73 remote pit thermometer in a couple weeks, and they are taking pre-orders for the ET-732 over at bbqequipmentstore.com.
"Here it is folks! The unit you've all been waiting for! We've gotten a lot of great feed back from all you smokees and came up with the second generation ET-73. The ET-732 has a range of up to 300 ft and can with stand heat up to 716 degs F and will display temperatures up to 572 degs F!! We also added... an alert feature to the Receiver to let you know if you've gone beyond the range, and a back light to the receiver for easier night grilling!"
