Hi, also kindly please would you tell me the difference between the Diplomat 5000 btu portable air conditioner & the Simplicity 5088 (5000 btu) - the picture of the Diplomat which i have seen looks identical to the Simplicity one which i have - is this the same make & model? Again, thanks kindly, Lea. (PS, if there is a difference, would you please let me know what they are?) - thanks again kindly :)
