We are comparing inverters from different places. For various reasons, we want to get one that is a 2000 watt (which can surge up to 4000 W) pure sine wave inverter. When I look at the jaycar catalogue, they are around $1500. When I look on ebay (at new ones) they are $200-300. Anyone have any thoughts on the difference?

Firstly I'm not an expert in this area.
2 main types
Pure sine wave - very useful if you intend to run electrical motors such as fridges and washing machines.
Modified sine wave - most other things will be fine.
Then you would want to look at efficiency figures, more efficient less wasted power and less heat.
I have a pure sine wave inverter rated at 2400W [12V] so I could run any normal household item. This is both backup and has the ability to be hooked up to a car battery if required.
I also have x2 UPS' one 4000W and one 2000W running on 48V. These units are my main power supply backup as they stay charged and turn on if they power turns off. I don't have anything on them, though a lead running to the shed [where it's stored] gives me power to the house if required. - the advantage of the UPS is that they're usually pure sine wave [check], I got them cheap [cost $75 & 50!] and they keep my batteries charged. They're also more than capable of handling the power output as the style I have are designed to always power what you have connected to it 24-7. Sticking a bigger battery bank on them is inconsequential to their operation.
