for those who use gas duster (gas in the can)to clean their computer or other stuff, this is a cheaper alternative in the long run.
check the review on amazon (there's another model called 500P, it's just different packaging - plain but more expensive, go figure!)
although this is 120v version, it's still cheaper even after you buy this transformer

(you only need 500w but just in case you need bigger wattage, just buy that one :P )

I bought one of these from BACS a couple of weeks ago. Got it delivered within 2 days of ordering.
Was considering the Amazon route, but too much mucking around with the transformer idea. I'd rather spend a few dollars more to avoid the extra clutter.
