I posted this twice. I thought I should add this in the Gear section because it has info that might help someone and I added a link to download the owner manual.
I ended up buying a 1,000W Pure Sine Inverter today from Canadian Tire on sale for $119.99 (Reg. price $299.99)
MotoMaster Eliminator Digital Power Inverter - Model 011-1892-4
If you are tempted by this deal make sure to read the specifications on the side of the box. The top of the box shows 1000 watts heavy Duty. The first one I bought without reading the specs on the side. I read it when I got home and it showed 800 watts continuous and 1000 watts for 5 minutes. I found a new owner manual online and to my surprise it showed 1000 watts continuous. My manual showed 800 or 900 watts continuous depending where you looked in the manual. So I phoned another Canadian Tire and asked that they check their stock and read out the specs printed on the side of the box. Theirs was 1000 watt continuous just like what I read in the new owner manual I downloaded. So I returned the first one. It was older stock manufactured July 2010. The second one I bought had a date of manufacture of November 2011.
The inverters looked the same and had the same model number 11-1892-4. Boxes look the same as well. Only visible difference is the specifications printed on the side and in the manuals.
Same box, same model number but big differences depending if you get older stock.
Old stock: 800/1000/1600
New stock: 1000/1100/2000
The older inverter manufactured July 2010 had 800 watts continuous and 1000 watts for 5 minutes and 1600 watt surge - see photo:
The newer inverter manufactured November 2011 had 1000 watts continuous and 1100 watts for 5 minutes and 2000 watt surge - see photo:
This 1000 watt pure sine wave inverter weighs 7 lbs. I have a 1000 watt modified sine wave inverter that only weighs 4 lbs. Heavier is better I think
It also has some nice features like the digital display, remote on/off switch and a USB outlet.
