GTMetrix is really helpful, but I didn't think it did different locations, but perhaps I just wasn't looking last time I used it.
Webpagetest is good, but, I've found it be slow, or more often inaccurate than others - but that might just be down to popularity and high load on their part.
Pingdom have a few US locations, and NL if I recall correctly, and are solid.
Can't think of any others off the top of my head.
