I've ordered from dragonusaonline before and I'm pretty sure they ship from the US. Been over a year though and ship-from addresses don't command much priority in long-term memory.
Shipping speed was about on par with most online retailers (save Sprue Brothers with their crazy fastness). My order, at least, was very well packed. In an actual box. Not like Squadron's common practice of "cut larger box into some vaguely rectangular shape and make it up with shipping tape".
