Eric,
I have used the expensive Klein models for Hazmat and they worked very well…good accuracy and distance.
For home inspections I simply have found the Harbor Freight model to be sufficient. I am not shooting great distances and am more concerned with seeing a temperature difference than anything. I use it to check for heat at the registers and hitting the fridge, frrezer, and oven for function. I use a digital thermometer with probe for temperature differential in the heating/cooling system.
To answer your question I would go with the Klein over the Milwaukee if you have narrowed it to those choices.
