[Elecraft] International shipping costs

[Franki ON5ZO]

Can someone please tell me if the difference in shipping is worth the 
difference in price to ship a KPA-500:

UPS Worldwide expedited = 414 $
US Post Office Priority Mail International = 131 $

I have had superb service from UPS with both my K3's but the difference is 
pretty steep and I need to pay 21% VAT on top of that!
UPS is fast (from clicking 'submit order' to K3 box in my hands in under 48 
hours), but I won't mind waiting a few days and save about 300 Euro if USPS 
is slower.

I wonder if USPS or their Belgian partner handles clearing the box through 
Belgian customs like UPS does. I have had nothing but troubles with these 
red tape lovin' kafkaesque bureaucrats, so I'd rather see the carrier handle 
the customs part. That would be in favor of UPS.

Has anyone in EU tried USPS and if so are you happy with it?
