I never worry if something I want is the US - no joke I have had stuff arrive from there faster than the UK's 1st class service gets things to me sometimes! So time is not normally an issue
I always make sure the price plus import duty and vat makes it worthwhile, if it is then I just do it! I have had watches, clothes, horse stuff, even a snowboard (which was picked up from the guy in the US Tuesday morning and got to us on Wednesday afternoon!)
