The key differences between the WH2000i (the one that was FP last year) and the newer WH2000iXLT model is that the XLT model now is parallel capable. Meaning you can purchase the parallel cable kit and wire it up to a 2nd WH2000iXLT to double the output power.

Alternatively, if you would rather purchase from Wayfair directly here is the link for that which is the same price: http://www.wayfair.com/Westinghou…7A
If you have a membership with Costco, I would recommend that you also check out the Smarter Tools AP2000iQ for $ 599 + $ 15 shipping. This is regular price and has been now for a while. It has a Yamaha engine (the same as the well known ef2000) plus you have Costco’s lifetime return policy. When I came across Wayfair’s sale I just figured I would post it since I haven’t seen the XLT version this low yet, shipping is free, and most of the US doesn’t have to pay tax on Wayfair purchases. So when you factor in all of that the difference equates to ~ $ 50. Plus there is the ability to earn eBay bucks.
