Also in the paint aisle at Home Depot, you can pick up
Denatured Alcohol, which will work great, and is what I use for fuel most of the time.
One thing, though - the stand for the Trangia Mini pretty much sucks. Definitely use some foil or thin roof flashing to fashion a windscreen. When I first got the Mini, I burned through an entire burner full of fuel without reaching a full boil, because it was windy and I hadn't thought to make a windscreen.
Better than just a windscreen, a clikstand (

It can even be used as a wood stove in a pinch:

I have been pimping out the clikstand big time lately, trying to convince anyone who will listen that it's an awesome stove - I was almost ready to give up on the Trangia Mini after I got it as a Christmas gift last year - I tried some DIY stand / windscreen combos and thought most of them sucked. The clikstand is light, packs small, and is crazy stable. It rules :thumbup:
Here's some generic picture of the stove in use from the clikstand website:
