[Test-Equipment] Shipping from Australia to US?

[davec]

Need to have items shipped to me here in the USA. Box will probably 
be 9x5x24 inches (21x12.5x60 cm) and weigh about 10 lbs (4.5 kg).

Is Austrailan mail an inexpensive and suggested means to get this box 
to me? Or should I use UPS?

Or...?

Thanks,
Dave
