That's because they don't want to get sued if you die.
Your machine doesn't really need a surge protector unless you have bizarrely unstable or unregulated electricity. The power supply is rated for normal operation between about 90 and 250 volts, which should handle most situations. In any case, a surge protector only protects against surges, which aren't really frequent unless your power is weird for some reason (like there's a machine shop in the basement or you run a welder or have frequent nearby lightning).
However if you have frequent brownouts or power failures, your best bet would be a UPS that's "always on" APC makes some models like this. There's no "switching time". They work by continuously charging the battery, and running the inverter.
These will smooth out your power, and handle brownouts and short blackouts, however the trade-off is that the consumer-grade stuff isn't bulletproof.
You would need to weight the probability of a failure of your home power against the probability that a $300 UPS would fail.
