[RE-wrenches] 2500 W inverter for $300

What your customers will find is that these auto parts store inverters 
only reach their nominal ratings with resistive loads. When trying to 
start a motor they exhibit a fraction of their rated power - too much 
reactive load. Same goes for anything with a transformer or power supply.

Also, if you take the cover off of one you will be unpleasantly 
unsurprised at the construction and workmanship. I've seen one with a 
"heat sink" for the transistors that was a paper thin piece of aluminum 
angle. You have to think that at $300 for 2500 Watts (supposedly) they 
used the very cheapest discrete components they could source.

Talk them down off the ledge.
