1800W equates to a 15A circuit - that's all you can get from the circuit. Something larger isn't any use unless you are putting it on a 20A circuit.

I use a Panamax MAX5100 for my surge protection. As a bonus, it provides some EMI/RFI filtration. A lot of folks use Monster's units and are happy with them, but Monster's array of overpriced interconnects made me wary of their stuff and I found the 5100 for a little over $200.
