Thanks Steve, just checked it out.
This got great reviews on some of the other retailers.
None of the other sites listed this though "Holds temperature for 4 hours and looses 1 degree/hour after that."
Seems like it is just what I need.
I found it a little cheaper, but not once you added shipping. For your above link my total will be:
Cart Total: $189.00
Shipping Costs: $13.80
Grand Total: $202.80
Seeing what I have spent on BBQ lately, probably should check with the wife first. Just missed my birthday!
