I have a bit of an electronics background and wanted to voice my opinion that Braindrain, boberonicus, and ScottC are exactly right.

When looking at power options the two factors you bring up, surge suppression, and circuit overload are two very different items.

Surge suppression is protection from high voltage spikes (transients) which may be present in the power mains. These transients may be as high as a thousand volts, but they occur for a very short time, typically one cycle at most. Inexpensive surge suppressors usually use one or more metal-oxide-varistors (MOVs) across the power legs which will short the power during these rapid events (I am very sure that's how the Tripplite you referenced handles surge suppression as 750 joules screams MOV). As boberonicus mentions, almost all modern switching power supplies are designed to handle these transients without a hiccup. Other than a direct lightning strike I have not heard of any cases of a modern laptop being fried by a voltage spike.

Circuit overload is a different matter. This is a true safety issue to make sure you aren't pulling too much power out of the building wiring. Unless you travel with your toaster, iron, heater, or other resistive loads this won't be an issue. ScottC is correct that overload devices like circuit breakers and fuses do not go hand in hand with "surge protectors" and you can find many different combinations.

I think it's a great idea to travel with your own power strip. It's nice to have several US outlets available without carrying a bunch of plug adapters (as long as all your devices can operate on 110-240V 50-60Hz). When selecting a strip just make sure that if there is a power indicator light that it can take 240V without going poof. That said I travel with a 4-outlet Monster outlets-to-go strip with a universal adapter plug. I'm in Australia about 3 times a year and Europe about once a year and this has worked great.
